Sometimes it's all, I guess, an exercise in faith, maybe.

Hoping this boosts my mitochondria.

At least I think it does.

So.

It makes sense to me.

I mean, I've heard you explain it, you know, multiple times and even the studies that, you know, Carrie Cunier was involved in that we kind of researched and you guys talked about in your podcast.

It's like exercise directly kills it, kills the circulating tumor cells, which I think is interesting.

Oh, I was wondering, you know, whether you think the stronger sort of risk reduction maybe from exercise in this study could have been due to just the fact that,

You know, cancer does have obviously a genetic and kind of environmental component.

So maybe that's why we're seeing that one to, it was like four maybe ratio instead of the one to 10 or one to eight ratio with cardiovascular disease or diabetes risk that we saw in this study.

Yeah, so then just moving on to, I guess we had two more mechanisms, sort of the hormonal cellular responses, as you mentioned, I think you kind of covered that pretty well, but obviously with these vigorous intensity activities, you get more adrenaline, more cortisol, more growth hormone.

Anything that you get with low intensity activity is sort of just heightened with high intensity activity.

Hence the idea that you don't want to overdo high intensity exercise because you get too much cortisol, too much adrenaline.

And if you don't let that recover and then go back to normal and do it again,

It could lead to burnout or overtraining, however we want to define it.

But you just get sort of this better hormonal milieu, I guess, during high-intensity and vigorous exercise that you get during low-intensity exercise, which I think explains probably the reduction in all of these different outcomes, diabetes, cancer, cardiovascular disease.

But the last thing I think that is important with vigorous exercise for, especially when we're talking in the context of older adults, is this muscle fiber recruitment.

So most people will be aware that muscle fibers are categorized into different types.

We have type one, which are referred to as slow twitch muscle fibers.

Then we have type two.
