Episode Date: September 12, 2026

Some very popular drinks can do a surprising amount of damage to your teeth. Which ones are the worst offenders? This episode begins with what certain drinks do to your tooth enamel and some simple ways to minimize the damage if you drink them. https://news.uthscsa.edu/more-u-s-teeth-susceptible-to-silent-enamel-eating-syndrome/ You are surrounded by gases every moment of your life. They fill your lungs, power engines, warm the planet and help create stars—yet gases may be the least understood materials in our world. Mark Miodownik reveals the fascinating and often surprising ways gases shape our lives. He is professor of materials and society at University College London and author of It’s a Gas: The Sublime and Elusive Elements That Expand Our World (https://amzn.to/3XDpcjX). People casually say they’re “addicted” to their phones, shopping, social media or video games. But when does something you enjoy—or simply do a lot—cross the line into addiction? And why are some things so incredibly hard to stop? Psychotherapist Talitha Fosh explains what really makes us get hooked and what it takes to break free. She is author of Hooked: Why We Are Addicted and How to Break Free (https://amzn.to/3XDW8sq).

There is one word, I think, gets people in trouble with money. It's probably. I'm probably spending about this much every month. I'm probably saving enough. I'm probably on track for retirement. Probably is not a financial plan. I've been using Monarch. It's a personal finance app that puts your whole financial picture in one place,

and it replaces probably with actual numbers. For example, Monarch showed me that, our spending last month jumped about 30% from the month before. 30%. We had some home repairs, but none of the bills seemed like a big hit at the time, but put them all together and, wow. But I didn't realize how much our spending had jumped until Monarch showed me. And I think that's how money can get away from you.

It's not necessarily one giant expense that sets off alarm bells. It's all the things that add up that you don't really notice. That's what I like about Monarch. You can see your spending, accounts, investments, and savings goals all in one place and see what's really going on with your money. If you're operating on probably, maybe it's time to find out, write your own money story with Monarch. Use code sysk at Monarch.com to get your first year of Monarch core half off at just $50.

Today on something you should know, what the drinks you drink can do to your teeth and what you can do to prevent it. Then the fascinating world of gases. You don't think about gases very much, but you wouldn't be here without them. We rely on gases for music. We rely on gases for hearing in general.

That's the waves going through gases is what we call sound. We rely on gases to get around pneumatic tires. Without them, bikes and cars won't exist. Also, the shoes you should and should never wear when you drive. And are we all addicted to something? The way I describe addiction is when we use something outside of ourselves to change the way we feel. Social media, shopping, you know, there's obviously the drink, the drugs, but we really can be addicted to anything.

All this today on Something You Should Know. A big thank you to today's sponsor, Vinted. I think most of us have what I call Someday clothes. I'll wear that someday. That'll fit better someday. Someday, I'll have a place to wear that. Meanwhile, it's been hanging in the closet for three years.

Today, Something You Should Know with Mike Carruthers. Yes, hi, welcome for Something You Should Know. I want to start today by talking about your teeth. Did you know that some of the drinks that you drink can literally erode your teeth, according to a study? Dental erosion is what this is called, and it can be subtle and hard to spot at first,

but over time too much of the wrong beverages erode the enamel, leaving you with thinner teeth, more sensitive, and more vulnerable teeth. Among the biggest dental offenders are soft drinks, fruit, and sports drinks, some herbal teas, lime-flavored beer, and seltzer fruit drinks. All of these drinks are acidic and will eat away at your enamel. If you do drink any of these corrosive beverages, you're better off using a straw and be sure not to brush your teeth right after drinking them. That just compounds the problem.

You should rinse your mouth with water or a mouthwash to get that stuff off your teeth. And that is something you should know. I'm sure you know you have a sense of what a gas is. You probably cook with natural gas. Oxygen is a gas. Carbon dioxide is a gas. Gases are everywhere. We wouldn't be here if it weren't for gases. But there are things about gases you likely never knew that are really interesting

and affect you in ways you're about to discover. My guest is Mark Miodovnik. He is a professor of materials and society at University College London. He's the author of a book called Stuff Matters, which was a big bestseller, and his latest book is called It's a Gas, the sublime and elusive elements that expand our world. Hi, Mark, welcome to something you should know. Hi, thanks for inviting me.

So I understand, obviously, you find the topic of gas is interesting, but why are we talking about it here? Why is it important for people to know and understand more about gases? Well, they are our life support system. I mean, that's an obvious, I suppose, so what, which is that we're breathing oxygen now, and without it, you die very quickly. But it's more than that. The emergence of oxygen on this planet was not, is an unusual currents.

I mean, if you see oxygen on planets out there in the universe, it's a very good sign that there's life. Oxygen itself is intertwined with living organisms. And it's a very reactive molecule. So if you look at the evolution of this planet and how life came to be, oxygen is a big part of that. But not just oxygen, of course, carbon dioxide. So carbon dioxide is the original molecule and still is a very important molecule for all life on the planet. And of course, you know, plants breathe it and many bacteria breathe it. And so, you know, we've got this dance with the stuff that we breathe.

and we live at the bottom of 100 kilometers of atmosphere. So in a way, we're at the bottom of a sea of gas. You know, you can think of us as little scuttling creatures. Above us is the ocean of gas. And that weighs down on us, actually. It has a weight 100K of gas, even though it's so light you can't really feel it with your fingers. It has a weight. And that weight is called the atmospheric pressure.

And that really affects the weather. So, you know, you've got life. You've got the weather. And then you just go into this whole world of gases that without which we would not have any of the technology we have today. So we rely on gases for music. We rely on gases for hearing in general, of course. That's, you know, waves going through gases is what we call sound. We rely on gases to get around pneumatic tires.

You know, without them, you know, bikes and cars won't exist. We, of course, the gas technology of gasoline. and of course there's jet engines, going to a hospital, you'll find loads of gases there, go into any scientific lab, we wouldn't be able to do our work without gases, and we wouldn't be able to work without vacuums, getting rid of gases. All the silicon chips in the world, pretty much all the kind of advanced technology relies on getting rid of gases during manufacture and having very, very pure vacuums. So, yeah, they're interesting.

But you mentioned gasoline. Now, gasoline is a liquid in my world. and yet it's called gas olines. Explain that. Well, there you go, because we pump it as a liquid. And actually one of the great things about it is that it has a high vapor pressure. So, and what does that mean in vapor? Well, vapor is when you get the molecules of the liquid going into the gas form at a normal temperature, our temperature.

and they do it very readily. And so when you take the vapor of the gasoline from your fuel tank and you mix it with oxygen through the carbolrata, that is the thing that gets put into the cylinder of the engine, and it's the gas form, the vapor form that's doing all the work. It doesn't work when it's liquid in that face. In fact, you can throw a match into a liquid gasoline and it won't ignite. It's only the vapor that ignites.

And in fact, flames and candles and all. They're all gas technologies. If you see a flame or you see a fire, you're looking at a gas. You just said that if I throw a match into a liquid bowl of gasoline, it will not ignite. No, it'll go out. Yeah, you need a mixture of oxygen and the vapor of gasoline. That mixture is what will ignite. Because what is ignition?

What is an explosion? What is fire? It's not just the molecule, in this case, gasoline, so it's a hydrogen. carbon, a sort of small hydrocarbon, it's basically a molecule with lots of carbons and hydrogens, you know, kind of attached to it. It's that reacting with oxygen. So for a long time in the history of the world, people didn't understand what a flame was. They thought it was actually a type of matter. And in fact, go back to the ancients and they thought that, you know, there were the elements were earth, you know, air, fire and water. And fire being an element. We now know that fire is a, is a, is a,

is a combustion. It's the reaction of oxygen with a vapor or with a gas. And so that's what you have to get. And that's why the hydrogen balloons that became the Zeppelins, the first airline ever existed was a hydrogen balloon going from Germany to France and then across the Atlantic to America. That was the first airline. That's in the early 20th century, late 19th century. It's an enormous balloon full of hydrogen. You'd think it was the most dangerous thing in the world. But because there's only hydrogen in there, it's not going to explode. It's only when it mixes with the air under certain proportions, and then you get a spark. That's when it becomes dangerous.

But the liquid, wait, but you hear about, for example, in a fire, gas tanks exploding. That's liquid gasoline blowing up. That's combusting. It's not a vapor. It's a liquid. Well, the liquid becomes a gas. The liquid itself isn't going to explode. it has to mix with oxygen

and then that has to encounter a high temperature, a spark. If it doesn't do that, it won't explode. And that's what an explosion is, by the way. An explosion is the formation of a lot of gas, like an enormous amount of gas in a very short space of time. So in a millisecond, you go from having a liquid to having something a thousand times bigger than that, which is what gases tend to be.

They tend to be a thousand times less dense than they're liquid. So you go from something the size of a bottle to something the size of a room in terms of the volume of that material in a millisecond. That's an explosion. So explosions are the production of a large amount of gas. So living creatures like human beings, all living creatures create gases, right? Sometimes in embarrassing ways, but we create our own gas. Yeah, I know.

That's the beauty of this topic, isn't it? No. Because it's so human. Not really. You know, like you can't write a book about gas without having odors and smells, you know, these are all the gases that are also, like, I encounter in the book. And, you know, they're all part of our lives and they're all either funny or, you know, crazy or weird or, but they are a big part of our emotional life. And I think that's the one

of the things I really want to make the point. Gasses as a subject is not just about technology and it's not just about science. It's about very, it's very much about the senses. First of all, Most gases don't smell. Most gases are invisible. Most gases you can't taste, smell, see, or touch. And that's an incredible thought because they're so important to us. For instance, methane. Methane is invisible and odourless, right?

It's not methane you're smelling. And in fact, if you're wondering why you can smell gas coming out of, you know, a gas leak, it's not because methane has a smell. It's because they intentionally put in a garlic smelling. odor into the methane supply. In all of that, we can all detect the smells, the leaks of gases. And so the gas in my gas stove is a gas. Can you make that or is it all natural? Because it's called natural gas, but is it all natural or can you manufacture it? You can manufacture it. There's a huge amount of manufacture of methane. So methane is the smallest hydrogen

carbon. So it's got one carbon and four hydrogens. And it's very related to gasoline. It's much smaller than the molecules and gasoline. So because it's smaller, it just has a higher boiling point. And so at room temperature, at normal temperature, it's a gas. And so you pump it through pipes and you can either make it from, you know, oil and gasoline, but it is a naturally occurring. So that's why they call it natural gas in the same way the oil is naturally occurring. So they occur together generally, and that's the gas form. It sits above the oil. In the old days, before that happened, because methane has an really interesting history in terms of use, because it wasn't used for heating first. It was used for lighting, and it was used as a form called, you know, coal gas. So they were

getting wood and coal and heating it up, and it breaks down. The carbon and molecules break down, and they have hydrogen there, and it gives off a gas, and that is methane. but it also gives off hydrogen. And that was being pumped around the cities of London and Paris in the early 1800s as the first gas lighting, as the first city lighting. Before that, all these big cities in towns and villages were dark at night. And they were very dangerous places. And especially London, you know, there's so much history of people getting killed and raped and assaulted and robbed. And it all happened at night in small alleyways in the dark.

And the citizens of London were absolutely. desperate for lighting so they can inhabit this wonderful city at night and not be and not be mugged. And it was methane piped through the streets onto lampposts that provided that light. And it's only much later that we started using it as a form of heating and as a form of cooking. And now, today, there's talk of banning gas cooking. So I want to ask you about that. I'm speaking with Mark Mio Dovnik. He is author of the book.

Do you wish you could just hit skip on the worst parts of your life? You know the same way you can skip an ad? I get it. I'm Siyaya and I live in Ice Cove. I've made some questionable decisions that didn't end up the way I planned. And today I'm still figuring it out. Somehow things usually get worse before they get better.

Apparently, that's how I roll. So bundle up and come along for the bumpy ride. Stream a new episode of North of North Tuesdays on CBC Gem. So, Mark, help me understand this whole thing about banning gas stoves. I've heard a lot about that lately, and there are a lot of people who are upset about the idea of banning gas stoves because gas is the preferred cooking method for a lot of people. So why is there a push to ban gas stoves?

So coming back to what the flame is, you see that blue flame when it's mixing with oxygen. So it needs to mix with oxygen and you get that blue flame. But every single methane molecule coming out of the tap is not combusting with an oxygen. So there's always a small proportion that are not doing it. And they're becoming other stuff. They're becoming things like carbon monoxide. And that's a very poisonous gas. Or they become small soot particles which circulate and you inhale.

and there's all sorts of, you know, different nitrogen molecules that happen at high temperatures. And so you start inhaling, if you're indoors and you're cooking by your gas stove, you're inhaling these. And, you know, I think until recently we didn't think it was a very big risk, until we had smart meters that could measure air quality. No one was really thinking about it. But you put an air monitor that you use to measure the street quality of the air,

and you put it next to your stove. and the red light will go up, alarm. It's the worst quality air you can breathe. So that's why people are starting to. I think we've just sort of lowered or increased, is that the right word? We've increased our desire for lower risk in our lives, right? We don't want to be polluted by the technology you be cooked with or light or drive around in. You know, all these technologies are now under pressure because they have these side effects.

Well, that's really interesting because I think I grew up. believing because I think the industry told us that gas was a very clean burning fuel, that you were, unlike other things, it all burned and so it all disappeared and you were good to go. Yeah, I think it's all relative, isn't it? So it's clean compared to what? So it's not clean compared to an electric hob, right? If you take the same meter, we do it in my kitchen because we got rid of our gas hob for this reason. and now the meter is green in our kitchen when we cook because we've changed our way.

But if you compare that to a coal or wood, yeah, I mean, it's far better. I mean, the amount of, I mean, wood fires are terrible in terms of pollution. And also the other thing, and this is a key gas point, is that the harmful things in it are all invisible. The nitrous oxides are invisible. The little carbon sub particles are invisible. The carbon monoxide is invisible. I mean, that's a really deadly killer. Well, since you swapped out your gas stove because of this, do you know, because I think people will think, well, it's okay because I turn the fan on above the stove.

So I'm good. Yeah, that's definitely a good idea. But where does that fan go? You know, like, I've looked at a lot of those fans, and some of them are really literally just go through a filter paper and then they recirculate it in the room. And that filter paper is not going to absorb those molecules. It'll absorb the little droplets of oil from your pan, which is the other thing. thing it's catching. Yeah. So unless the fan is basically taking that air and venting it to the outside, you're not doing yourself any favors. So what is a gas that we haven't talked about yet

that you think is really interesting and we should talk about? The one we haven't mentioned, that's the big one, which started the whole industrial revolution of, is steam. And really, the steam story is so fascinating. I couldn't do justice to how incredible it is, because Like, you just have to write a whole book on it. But Steam is this moment in history where we're trying, you know, there's loads of inventors out there who understand that if you can make a machine that can do the work of a horse, or you can make a machine that can, you know, you put energy in and it'll pump things or rotate things, that you'll change everything.

But no one could get one to work. And then 17th, 18th century, little inventors in Britain and in France, because it's where, you know, a lot of the work is being done, suddenly crack it. And you get this early, very clunky steam engines that are just pumping water out of mines. And the reason why pumping water out of mines is important is because these are very deep, lot holes, which, where we're mining coal, we've cut all the wood, we've cut all the trees down. So we need wood for cooking and for heating. So we're starting to burn coal.

You've got to get coal. You've got to make a mine. But if you live in Britain, they fill up with water because it rains a lot. So you have to pump the water out of mine. if they're doing it with horses, then they found actually you can make a steam engine do it. If you make this gas, you create this gas by just heating up water, it pushes a piston. Well, actually it doesn't. It sucks a piston because of atmospheric pressure.

And this is the big discovery, is that you turn it from a gas to a liquid by cooling it. That creates a vacuum. That sucks the piston down. And then you push gas back in. That's the condensing steam engine. And then, oh my God, then they suddenly realize, whoa, we can just do much more than a pump. jumping, we can start to go places. And the thirst for a car, steam car happens in the 18th century. It takes 100 years to make one and along the way they find out something else. Actually,

the best way to use steam for transport is not a car. That's really difficult because it's a big engine. It's very heavy and the roads are bad and you can never get it to work and it took them so long. But what work was go on water because water can take the weight. It doesn't make any difference. and there's a big advantage to be able to go against the wind with steam. And so you get mass travel. Then suddenly people are going across the Atlantic from London to New York, from Paris, and it opens up the population's idea of what it is to be human. You can travel the world.

And of course, you get mass migration into America, notably. And this changes the whole trajectory of America, you know, like all these people coming from Europe. But then the railways are born. And so then you get onto solid ground and it turns out you don't want a car, you actually want a railway because the iron rails can take the weight of these massive engines. And it's much, much later than the car comes along. And by the time the steam car is born and can really do it, they've got the technology down, gasoline comes along,

and the internal combustion engine blows it out of the water. And steam disappears. But it's such a shame because it basically for 100 years was preeminent. And if you think, well, God, I love steam. And it's true, I think if I, you know, there is something about a steam engine that is, that really delights the engineer in me. And I think everyone, it's got a very human quality to it, the steam engine. It's, it huffs and puffs and, you know, like us, you know, it emits things. It seems to have emotion.

So, you know, yeah, I think steam is definitely one that we should never forget. I was surprised to learn that nitrogen is so important. And it's a pretty interesting story. so tell that. So half the people on the planet alive today owe their lives to a gas that's in the air. It's called nitrogen. So you breathe it in every breath, but it's only the oxygen that you're taking. The nitrogen, you breathe out again.

But we need nitrogen because, look, DNA, like proteins, you know, it's all made of carbon, hydrogen and nitrogen, right? So we need nitrogen. All life needs nitrogen. So where do we get it? from. We don't get it from the air. We don't breathe. We don't metabolize it by breathing it in. There are only very few organisms that can actually do that. And they're these sort of bacteria that exist in the soil. And all our nitrogen comes from them metabolizing it, dying and being,

you know, made into plants, plants being eaten by us or by animals. And that's how we get our nitrogen. Now, basically, once you've used up your nitrogen from the land like that, you start to starve. This is a problem for all high density populations because they end up basically exhausting the nitrogen in the land. And it was recognized in the 17th and 18th century as a real problem. And they started using bird poo from places like Peru and Chile, like digging it from these very dry places and shipping across the world. And when that ran out, they started mining the small areas of the world where there's some mineral nitrate minerals, but again, they run out. And there was a guy, a German, who basically worked out a way of taking nitrogen from the air using a chemical

reaction, very, very dangerous one, and making it into fertilizer. And his achievement, he's a very checkered figure. In fact, he's also the father of chemical warfare. So, you know, World War I, he's a, but now today, you know, that process of making fertilizer from the air is, you know, it's put on almost all the agricultural land. The only stuff it's not put on is organic farming. And without it, I mean the latest calculations are that half the population of the world would not be able to live. Like we would not have enough food without that one discovery. Okay, well, now I understand why you study this and why you write about it and want to talk about it. Because there's a lot to learn.

And what you said about natural gas stoves and why you switched yours out is certainly something for people to consider. Mark Mio Dovnik has been my guest, and he is a professor of materials and society at the University College in London, and author of the book, It's a Gas, the sublime and elusive elements that expand our world. And there's a link to that book at Amazon and the show notes.

Or even can you be addicted to your work? These are things that consume a lot of your time. they're often hard to stop doing, and you do them for not always the best of reasons. Sure, there are addictions to drugs and alcohol. Those are true addictions,

but are these other things really addictions? Or are they just a way to pass the time and are hard to stop? That's what Tolita Fosh is here to talk about. Tolita is a psychotherapist who works primarily with addiction, and she is author of a book called Hooked, why we are addicted and how to break free. Hi, Toledo. Welcome to something you should know.

Thank you so much for having me. So let's start with what an addiction is because I think of an addiction like drugs, alcohol, nicotine, these are things that your body really needs and it's hard to break free. Whereas, you know, the social media or shopping or spending too much time at work, they don't feel like addictions to me. they just feel like ways to avoid doing something else, and maybe you're getting something out of it, but it's not a true addiction. So help untangle this.

Well, I think that in today's society, there are so many things that we can get a hit out of, you know, any kind of high. The way I describe addiction is that when we use something outside of ourselves to change the way we feel. And so if we're looking at it on from that perspective, it can really be, we can really use anything to change the way we feel. So social media, shopping, you know, there's obviously the drink, the drugs, but there is, you know, even there is this doctor called Dr. Lemke who talks about the fact that she was addicted to romance novels. And she, she realized that she was addicted to them because in between her patients, she would pick up her romance novels as a way to distract herself

because she was having uncomfortable feelings. So if we look at it in that lens, we really can be addicted to anything. Video games is another one because all these things that we have that are so accessible to us, they all change the way that we feel, essentially. So I wonder where, though, is the line?

Like, my son plays video games. He loves to play video games. But he can stop and, you know, we'll go do something. I mean, it doesn't seem like an addiction, but maybe if I left him alone, he'd play all day, but he doesn't. So the way, I mean, because obviously, you know, it's important that we have things that we use to sort of take our mind off stuff. You know, if we've had a hard day, you know, playing a video game isn't a bad thing. It becomes a problem when it makes our lives unmanageable. So when we're unable to do the other things in our life that we like to do because we're

stuck playing video games. And video games is a great example because, you know, obviously it's increasing in popularity and it's one that is sort of acceptable, oh, I'm just going to play my video games. But actually, if you're not careful, you slowly realize, okay, I'm going to choose to play my video game rather than going and seeing my friends. And then I choose it again and again. And before I know it, I've become very isolated. Or I don't manage to get my homework in on time because I'm playing my video games. It's those kind of unmanageabilities that with what we call behavioral addictions is much harder to see at the beginning. Because obviously with drink and drugs, when your life becomes

unmanageable, you know, it's quite obvious, you know, because you're drunk or you're high. But with behavioral addictions like social media or gaming, as you say, the problems can start off a bit more subtle. And I guess also if you think about, if it's causing problems and you're still doing it anyway, then obviously it's also become a problem. Yeah, I like that definition. If it's causing a problem and you're still doing it anyway, then you got a problem. Yeah, absolutely. I mean, yeah, If it's destructive and you know that it's wasting your time or causing you pain and causing other members of your family and friends pain, then I'd say definitely, you know, it's making your life unmanageable and that it's probably a problem. But it does seem that there is a difference between physical addictions like drug and alcohol, where if you do stop, there are physical symptoms. You go into withdrawal and it's really horrible versus if you stop playing video games, pretty soon.

you kind of forget about them and you go off and play baseball or whatever you do, that those are very different. Absolutely. I mean, obviously with the drugs and alcohol, there's a chemical addition, you know, in our brain chemistry that's being altered. And so when you stop that, you do go into a much more severe withdrawal. However, when we are engaging with any type of behavioral addiction, we are also releasing dopamine. Now, that dopamine is obviously going to be less from the behavioral addiction than what we are getting from if we're using drugs and alcohol. But pain and pleasure come from the same part of the brain. So every single time that we get a hit

of dopamine or every single time that we get pleasure from something, at some point, we will get, we will experience pain, which is what, you know, we've called a withdrawal. Now, as you say, these levels will vary. But in order for the brain to get back to what's called homeostasis, which is the sort of level playing field, this kind of, yeah, equilibrium, we will at some point experience pain. I mean, I think about using social media, for example, and I have clients who do this where, you know, you get stuck scrolling. And even though you don't want to be scrolling, you keep scrolling and it's really hard to pull yourself away from your phone, from the scrolling, even though it's way past your bedtime and

you don't really want to be doing it anymore, you feel like you can't. And actually to pull yourself away from, to pull yourself away from it can feel like a bit, you know, you can experience sort of apathy or you can experience a bit of a low. And that is usually because you've released all this dopamine with the constant swipe or the constant scrolling. and then eventually, you know, you will have to feel that kind of, oh, God, that withdrawal in order for your brain to level out. Now, sort of, there's not a time frame as to how long it takes for your brain to kind of come back to homeostasis, but a lot of people say, I mean, obviously with alcohol and drugs, it's abstaining for good. But with behavioral addictions, it's about 30 days for your brain to come back to that homeostasis,

for your brain to come back to that level playing field. So 30 days without gaming, 30 days without your phone. But in that time, it's a very interesting experiment if you think that you are addicted to something or that you use something a little bit too much to try and abstain for it for 30 days and see what happens. And is that the prescription?

If you have a behavior that's causing you trouble, the best thing to do is just stop cold turkey? Yes. I mean, obviously, drugs and alcohol is very different, and I have to sort of, obviously, a disclaimer if you are sort of thinking of abstaining from that, and you need to seek medical advice if you've been using it for a long time. But I'd say, I mean, yes, let's say a broad prescription would be to stop the 30 days so that you're able to notice as well. When you stop something, you're really able to notice why you might be doing it or what feelings that you might be experiencing. that might be causing you to do it in the first place because if we sort of go back to this definition of addiction that we're using something to change the way we feel, we need to know what's going on underneath. And 30 days is a very good time to start with.

I mean, I would always say probably a bit longer, but brain chemically, I'd say start with 30 days and see how you go. And actually, if I think about the example from this doctor, that I was talking about who was addicted to romance novels. She started reading, after she had given birth, she started reading these romance novels to help her kind of go to sleep. They sort of soothed her. And then before she knew it, she was taking them into work

and reading them every 10 minutes she had in between patients. And I think the question was, oh gosh, she eventually took time away from these books. She had, I think, 30 days or something. So she was able to figure out, okay, what else is going on underneath? Okay, I'm struggling with being a mom or I'm, you know, struggling with all my hormones and feelings. But the only way she was going to figure that out was if she took time away from these books. And eventually, that's not to say that I'm sure she's reading books again.

It's not that she can never read them again. But it's a very good sign of perhaps what might be going on underneath and something to explore. So I often wonder, well, first what I wonder is, are people scrolling on their phone and playing video games because it makes them feel good or it prevents them from feeling bad about something else? And the second part of that question is, and if they stopped and thought about it, do you think most people would know the difference? That's a very good question. And I think it's probably a bit of both with lack of awareness, if that makes sense. So we start doing something because it makes us feel good. And then we continue doing that thing because it probably makes feel good,

but it also distracts us from, you know, other things that are going on in our life. I mean, if I use myself as an example, because, you know, the reason I started working with addiction is because I'm an addict myself and I'm coming up to 10 years clean. And for me, it started off with food, you know, change. changing my food, restricting my food. And it made me feel good initially to do that. But the reason I carried on restricting my food was because I then realized, oh, this gives me a sense of feeling in control.

This is distracting me from other areas of my life that are perhaps difficult at the moment. And then at one point, you know, it takes over and it becomes, you know, very difficult to then stop. But I think it's probably a mixture of the two. Something I think people wonder, I wonder about this sometimes, because I'll, you know, I will sometimes be in bed, maybe starting to scroll through social media. And I know I should go to sleep, but I kind of can't stop, but it doesn't happen very often. But when it does happen, I think, God, do I have a problem here? And then when I put it down, it's fine.

It's like, well, why didn't I stop 20 minutes ago? You know, nothing great happened in the last 20 minutes. I should have stopped a long time ago. It's very occasional, but then you think, well, gee, I mean, this, what's going on here? Well, it's a good exercise when that happens, because I usually find this for myself. You know, there are times where I can, you know, be on social media for, I can pick up TikTok, for example, or Instagram and have no intention of being on it, but be on it for a couple of hours and then think, oh, my God, that's not what I wanted to do, you know. Right, right. That hasn't been a very successful evening.

You know, I had plans, right? What I usually then ask myself, and I'll ask clients to ask themselves, is what went on that day, you know, was there something that's been going on that day, that week that you needed to numb from? You know, it might not be anything in particular, but you might, you know, we are so automatic to pick up our phones anyway that sometimes we don't, you know, sometimes there might be no. reason, but sometimes it might be like, okay, we needed to numb ourselves a little bit more today because we're feeling a little bit stressed about work or sometimes, if anything, it's, oh, I'm feeling a little bit more tired, ironically, because we're still on our phones. But it really helps, I mean, I'm not sure if you've experienced this, but it really numbs us out. You know, when we're swiping and, you know, scrolling on our phone, we're really not thinking about anything

else. It's just these constant bits of content that are giving that hit of dopamine, especially on TikTok now. These short, sharp bursts of content are designed to get us experiencing more and more dopamine. So it's very difficult for us to take ourselves away from it, to pull ourselves away from it. But if you find that there's a time or, you know, one evening, it's harder than another evening. It's worth figuring out, okay, or worth asking yourself, is there any, is, am I? Am I? more, am I more tired today? Am I more stressed about something? Do I need to talk about anything? Do I need to express anything? Those kind of things can help us. Because, you know, there is sometimes no reason as to why that happens. When it does happen, when it does seem like it's more than

just an occasional thing, when it does seem like you're asking yourself, do I have a problem with this abstaining is, it isn't a matter of trying to cut back. It's kind of like, I kind of reminds me of like, you know, cigarette smokers trying to smoke fewer cigarettes. It's just, yeah, that doesn't really work that well. Unfortunately, with, as I said, with sort of with alcohol drugs and cigarettes, abstaining is really the only way forward, abstaining completely, because as soon as you've had a sip of alcohol or any kind of, or a toke of a cigarette, you've, you've activated that addiction again, and it's very unsafe, you know. So that, we're in, we're if we're talking about chemicals, drugs and alcohol, nicotine, to abstain for good is obviously

the only way into recovery. It's a little bit more sort of, there's a bit more of a gray area with behavioral addictions because, you know, we have to be on our laptops to email. We have to, you know, we have smartphones are everywhere. So it's about sort of starting for, I'd say to start for 30 days, Also, there are other things that you can do to help minimize the kind of exposure you're getting to the behavior. So for example, you know, if you are addicted to smartphone, I had a client who is addicted to smartphones and all the apps and everything, you know, being very activating and triggering all the time to getting an old school flip phone, you know, one that doesn't have all the

thousands of apps on it. That can be a really good way. You know, with like food disorders as well. you know, we have to eat. It's not black and white. So it's about, okay, how can we come up with a program, like a plan, like an abstinence plan, it's called, to put in place something that you stick to, that you don't, like basically boundaries with yourself that you stick to with the help, with the help of a therapist or the help of a rehab or whatever, that you don't break so that you have an abstinence plan that makes you feel safe and keeps you staying away from engaging in any

addictive patterns, basically, or destructive behaviours. But if you don't feel that your life's that unmanageable, but you'd like to try, you know, abstaining for 30 days, definitely a good, a very good place to start. And just to notice, you know, notice what happens, how you feel, notice the cravings, because you'll get cravings. I mean, I certainly notice when I put my phone down, but I'm like, okay, no more phone for the rest of the day, I will know. notice myself trying to look for my phone automatically. You know, it's like, where's it gone? Is there any sense, or do you know, or do you have a feeling since you talk to people

who suffer with this, that if you have one, you probably have more than one of these kinds of addictions? I believe that if you suffer with some form of addiction, whatever it is, then it will most likely pop up in other areas of your life. I mean, that was certainly my experience. and with most of the, in fact, I think it's safe for me to say all of my clients that I work with, who suffer with addiction of whatever kind, once they put one addiction down, another one will pop up. They can be less severe.

So, for example, putting down your addiction to alcohol and suddenly becoming addicted to exercise. Obviously, the addiction to exercise is much less harmful than the addiction to alcohol. Any idea why some people have no problem and others do? Why some people don't fall victim to, they can play video games and stop on a dime and say, sure, yeah, I'll stop. That's not a problem. And other people cannot. It's a great question.

For me, it always comes down to nature versus nurture. There is proof and research to show that it can be genetic. So with alcohol, for example, there are different genes. that can make you more susceptible to being an alcoholic. So that's definitely part of it. And if, you know, people call it an addictive personality. If that runs in your family, then of course you're much more likely to fall victim to that.

The other part of it is the nurture element to it. And this is all really about childhood and growing up and how your needs were or were not met. Because, you know, between the ages of 8 and 12, most specifically, we're developing our sense of self, who we are, what we like, what we don't like, how we interact with our peers. And at that point, if our emotional and physical needs are not met, we make it mean something about ourselves. We think we're not good enough. We don't believe we're lovable. And we develop these negative belief systems about ourselves. And what I've seen so many

times is that these things happen, you know, our emotional needs aren't met when we're younger or physical needs. And then as you grow older, you take these negative belief systems with you. And then, you know, we're then not going to behave in ways that are kind to ourselves or that are loving. We're going to, we end up behaving in very self-destructive ways because of these negative belief systems that we carry. If I give a very simple example, if you're upset about something as a kid and you go to your parent or caregiver and say, you know, let's say someone was mean to you at school, so-and-so said this to me at school and I'm really upset about it. And a parent or caregiver says, oh, well, don't be silly. You shouldn't feel like that. That is an emotional need not being met.

The child needs to be validated on some level, on some level, and feels very confused by the fact they're being told not to feel a certain way. And we internalize that and we think, oh my God, there must be something wrong with me, what's wrong with me, I'm unlovable, etc., etc., etc. And these things do stay with us, these negative belief systems, unless they are challenged later on down the line. Well, I still wonder if scrolling on Facebook or shopping is really an addiction or it's just something to distract yourself so you don't feel bad about something else. And as you say, it is a sliding scale, but well, it's a lot to think about. Tolita Fosh has been my guest.

She is a psychotherapist. and the name of her book is Hooked, Why We Are Addicted and How to Break Free. And there's a link to that book in the show notes. Thanks to Lita. Thanks for coming on. Oh, great. Thank you so much. The type of shoes you wear when you're driving really can make a difference.

And there are several types of shoes you really probably want to stay away from. Probably the worst type of shoes to drive in are flip-flops or really any kind of sandal. because they have the potential to just come right off your foot, and then the flip-flop or the sandal can get stuck under the pedal, and that can cause all kinds of problems. Thick-souled shoes aren't so good either. Thin-sold shoes keep your feet as close to the pedals as possible, making them better suited to helping your feet gauge the proper amount of force needed to work the pedals.

When you drive with thick-sold shoes like wedges, platform shoes, or even heavy boots, it could cause you to miss a pedal or press two pedals at the same time or use the wrong amount of pressure. High heels are kind of a nightmare too, and considering how cumbersome high heels are to walk in, it probably comes as no surprise that they're not very good to drive in either. When you're wearing high heels, you only make contact with the floor at a very tiny point,

a very small surface area, which means the shoe could slip. Plus, high heels force you to position your feet in unfamiliar positions, and the shape of the shoe can make it also difficult to apply the necessary pressure. Well, so you might be tempted to drive with no shoes, but when you're used to driving with shoes, driving without them can feel foreign, and that's not what you want when you're driving. Barefoot driving requires you to put more pressure on the pedals than you usually do when you're wearing shoes. So what should you wear? Well, ideally something like sneakers or flats or loafers, those are the best shoes to drive in. And that is something you should know. You know, every new

I get it. I'm Siaia and I live in Ice Cove. I've made some questionable decisions that didn't end up the way I planned.

And today, I'm still figuring it out. Somehow things usually get worse before they get better. Apparently, that's how I roll. So bundle up and come along for the bumpy ride. Stream a new episode of North of North Tuesdays on CBC Gem. Thank you.
