This is the coolest thing about science about biohacking. We're rediscovering ancient knowledge.

I started running an anti-aging nonprofit group, which is why I wrote Superhuman, the new book about anti-aging.

Bulletproof took off in biohacking. I wrote Superhuman, the new book about anti-aging.

Bulletproof took off in biohacking, by extension,

first with these two really focused populations.

One was entrepreneurs and software developers,

and the other one was Wall Street.

These are people who have to have brains that work all the time

and would like to look good or sometimes have to look good.

But it's all about do I have the energy to bring it, do I have the world power?

I spent a million dollars and God knows how many

thousand hours because if someone had told me this when I was 20 I would have taken

all the energy to win this and put it into something else useful. I was old when I was young.

I used to be 300 pounds.

I had arthritis in my knees when I was 14.

Constant antibiotics,

I would have sinus infection or strep throat.

Do you know that I worked out an hour and a half a day, six days a week, and I went on a low-fat, low-calorie

diet the entire freaking time? It didn't work. I did everything you're supposed to do.

So I'm sitting here going, what the heck? I got to work on this and decided that I would

I would hack it.

So now 20 years later, I've been studying and learning and immersing myself in that field to get the skills and the knowledge that led to bio hacking,
