Another reformed physician, medical doctor, that's doing other things. Really, really phenomenal guy. So Peter created this postgraduate university, Singularity University, that teaches exponential thinking. And so what exponential thinking is, is it's using exponentially improving technologies to solve different problems. And so what's the first exponentially improving technology is a computer chip, semiconductors. So semiconductors—and we think of it as Moore's Law, you know—are improving in price performance, doubling every year and you think about the difference between doubling of, you know, if you take 10 steps, he moved 10 steps forward, if you take 10 exponential steps, you move 1000 steps forward, move that to 20, it's a million. Move that to 30. It's a billion. So it's, it's really a whole different way of thinking, and our brains don't think exponentially. But if you start to think exponentially, and you get on the ride of exponentially improving technologies, all of a sudden, problems that for all of humanity, we couldn't even... maybe we can imagine... I should say, in science fiction. But all of a sudden, they become solvable. And they talked about in that curriculum, one of the problems being aging, longevity. And, you know, as a medical doctor, I had never thought about that. It's not the way that they talk about it at all. They talk about it's a natural phenomenon, there's these different diseases that you would target. But the concept of targeting aging process, like, "oh, my God, that's what I want to do." And so right at that time, so this is 2016, not that long ago. These reports out of academic labs were starting to come out where we are successfully, scientists, successfully extending the healthy lifespan of model species by, in the case of worms, it's ten times the natural lifespan of a worm, by one gene change and caloric restriction. Ten times their natural lifespan. And very similar changes in mice two times their natural lifespan. Now, mice and us share 98% similar genes. Like it's remarkable. So you think about that, if we can translate that to humans. Wow. Right, it changes humanity. And so I, immediately when I read about this was like, this is what I want to do. I announced it to my network, and just started getting introduced to people and just went back to like reading, picked up every single journal article that I could, and I hadn't read a journal article in a while. So like, getting back into that kind of scientific analysis and then going to conferences, meeting the scientists. And then I met other entrepreneurs interested in this space, other investors interested in the space, and started looking at different projects. And with my medical degree, my success as an entrepreneur, I got introduced to a bunch of people. And so it looked at a lot of things. And I looked at this from two different perspectives initially. I was like, well, first of all, the concept that I really want to get across this audience is aging is malleable. Okay, there's no question about it. Not chronological age: you cannot do anything about that number, right? But your biological age is absolutely malleable, right? There are things that you can do that accelerate your biological age, like smoking, like being sedentary, like eating a bunch of sugar, or overeating. And there are things that can actually reverse your biological age, actually improve it. And so this is... and you know, exercise, mindset, proper nutrition, getting sleep. Okay, so really, really important.
