Circadian Mechanisms and Longevity

What's the other part? What are the two things

that control the circadian

mechanism? Light and temperature.

What's the temperature, Mike, at 20,000 feet in Nepal?

Is it the same as it is in El Salvador at the, the beach?

No.

So guess what? All these things are built into that system.

So

I would say to you as a guy working out in the gym, even if you're doing it the

right way, are you using cold and UV light to

actually get that set point of your basal metabolic rate right

so you can go long-term? Because one of the things

that I've argued both with

Yurin, Peter Attia, Sean Baker, all those guys,

is

they think that having big muscles is a benefit. I'm gonna tell you it's not.

It's a detriment to longevity.

And the reason why is we're not designed to put our

mitochondria in our muscles.
