And their capacity to do that was reduced by 50% after such a short intervention. So I think sleep restriction and unhealthy sleep is a very underappreciated cause of metabolic health and weight gain. And then by extension, these other things we're talking about.

Yeah. I mean, look, I've said this before and I'm not the first to say this, so I'm paraphrasing others, but if you really stop to think about it, sleep doesn't make a lot of sense from an evolutionary perspective. Right. Like if you go back in time a few hundred thousand years, why would we have spent a third of our life unconscious? It didn't serve our purpose.

You can't mate, you can't hunt, and you can't defend yourself. So you have to believe that if we could have evolved out of it, we would have done it. And we didn't. So that means that whatever it's doing, it must be really important. I mean, core essential to our existence. While I will completely acknowledge that different people have a different necessity or requirement for how much they sleep,

I still think that many people underestimate how much they need.

Well, they're very similar to the types of things you're thinking about, and I love how you've got specific examples. So I really like playing with my kids, right? So I can imagine that in my marginal decade, I'll have grandkids that are the age of my kids, right? Yeah. And, you know, maybe a bit older, but as I'm even getting towards that marginal decade.

Okay, so playing sports is really, really fun. I really like playing, especially because when I grew up, like I played hockey because I grew up in Canada, and then I immediately went into kind of boxing and martial arts, and those became my life. So now playing sports that I didn't play much as a kid is really fun. Like I'm really enjoying baseball. I'm really enjoying soccer. And –

And so when you play these things, you realize this is not an easy thing to do when you get old. Like to sit in the goal and actually like stop a ball when a kid is blasting at you full stop, you have to be able to move around. So again, like I would love to be able to play soccer, throw a football, throw and hit a baseball as long as possible.

You can get into movements that are much simpler, but if I can do all of those things, I'm in great shape. Now, of course, to be able to do that, I also need to be able to do a lot of things that many people also can't do in their marginal decade, like sit on the floor, get up off the floor under their own power, walk up X number of flights of stairs, having the strength to do that.

I like doing that. certain things. Like I like archery a lot. So it's, you know, I want to be able to pull a bow back, obviously not at the same poundage as the current bow that I pull back, but I would still like to be able to pull a 50 pound bow back in the final decade of my life.

No one in the final decade of their life ever said, I wish I had less strength and I wish I had less endurance. So you cannot be too strong and you cannot be too fit. The only time that one would throttle back on the pursuit of those is A, if doing so is coming at the expense of something else, either with respect to your health or your life.
