you know, electric can openers and you name it, right? And so basically now we don't really need to be physically active anymore, and yet our bodies require physical activity in order to turn on a whole variety of repair and maintenance mechanisms that keep us healthy. And so we've had to create in the modern industrial or post-industrial world this really weird behavior called exercise.

Which people resist like crazy. Yeah, and there's nothing wrong with them, right? It's normal. I mean, I think one of the problems with the way we think about exercise is that we make people exercise about exercise. We make them confused and anxious and feel bullied and shamed about it, right? But it's a fundamental instinct not to do physical activity unless it's rewarding or necessary. And

And so we need to be more compassionate towards our fellow human beings who are struggling to do something really weird, like get on a treadmill and run for five miles and get absolutely nowhere in a really kind of, let's face it, a very unpleasant kind of context.

That's exactly the point, right? Which is that we evolved to be physically active, you know, not a crazy amount, you know, two to three hours a day, basically. But that's a normal part of our environment, right? And when you remove that, then all of a sudden, all kinds of natural mechanisms which our bodies mount get turned off. And so...

And so we often say that exercise is medicine, but a really more accurate statement is that the lack of physical activity makes us more vulnerable to disease and accelerates the aging process. So exercise isn't really actually medicine. It's the lack of exercise that causes problems.

Yeah, I mean, I think we sometimes exaggerate that stuff. I mean, look, if running was that dangerous, you know, then there could be no runners left, right? You know, I think we sometimes exaggerate injuries and that sort of thing. I mean, it is true that people exercise has trade-offs. Everything has trade-offs. There are costs and benefits to everything.

And so injury is always a potential there.
