It protects your telomeres.

It optimizes all these longevity switches like AMPK, which regulates blood sugar.

People say, oh, I'm going to take metformin for longevity.

Well, exercise is way better than metformin for regulating AMPK.

It also activates sirtuins, which help DNA repair, reduce inflammation, and improve your blood sugar control, which are really important.

It also improves...

Your cardiovascular and heart health, we all know, it reduces the risk of heart attacks and strokes and improves your brain function and cognitive function.

It also helps certain types of cancer, as I said.

We see the regulation of our biology through exercise being meted through all these mechanisms that have to do with immunity and cancer prevention.

So it's super great.

And of course it extends your health span and your lifespan.

I remember being in Sardinia and I mentioned this guy, I think before, but his name is Pietro.

He was 95 years old.

And he was like a shepherd and he was just running up and down the mountains all day, five miles a day in this really rugged terrain.

And he was bolt upright, you know, booming voice, clear eyes, you know, strong and mentally sharp.

And I was like, wow, this guy's 95 years old.

You know, most people 95 in America barely can kind of walk across the street or get from their bedroom to the bathroom.

And here he is, you know, running up the mountain.

So we have the ability to do that.

And he exercised every day as a shepherd, not quote exercise, but he just, that was his life.
