And there's two other studies, large scale studies, besides the first one that say the same thing. So the idea of eight hours a night, it's a myth.

That study, they collected data in the 80s. It was a very large amount of data. It was so much data that no one could process it. And someone dusted it off sometime in the early 2000s and ran it through proper computers and was like, oh my God, look at all this. And since then, it's been confirmed twice. Interesting.

So if you wake up and you feel rested and good to go and your heart rate variability is there, and you only got seven hours of sleep, good for you. Regularly, like tens of thousands of people have reached out over the years saying, damn, I went on the Bulletproof Diet, I started biohacking, I need an hour less sleep, is that normal? I'm like, yeah, welcome to being healthy.

What is your... I put a bite guard in. This is critically important if you're going to live a long time. As you age, your molars wear down and it changes the angle of your jaw, which screws up your whole nervous system. Those were my first 10 podcasts like 14 years ago.

Yeah, because if the angle of your jaw changes, it changes the pressure in your trigeminal nerve, which is right next to the vagus nerve. So the inflammatory cytokines from the trigeminal go to the vagal nerve, which controls rest and digest and fight or flight. And if you want to live a long time, maintain the height of your molars. And you do that by wearing a bite guard at night.

I had to, like James Nestor did, who's speaking at the conference, I had to expand my upper palate, bring my lower jaw down, forward and raise the height of my molars for my nervous system to work right. Because we have malnutrition of mothers, in large part from all these grains and all the other things, a lot of kids are born with a crowded palate and teeth that don't fit.

So your nervous system will never work right until you fix it. That was a big shift for me.
