Bryan Johnson spent millions collecting detailed biometric data on his own body, then used peer-reviewed research to design interventions targeting aging. After two years, his biological aging rate dropped below a ten-year-old's. He explores what's possible if scientific progress continues at its current pace over the next twenty years.
If you just basically made my body a controlled experiment, what could you do with the body? Like, how much could you slow the speed of aging? I spent millions of dollars doing the first step of measuring everything we can. So we use mri, ultrasound, DNA, methylation, microbiome, everything we can measure. Then we look at the evidence and we say, what does the evidence say to do to how to achieve optimal health? And then we implement it. We've dramatically slowed my speed of aging. I'm now aging at a rate slower than the average 10 year old. We've been able to do that with just two years of playing around. It's reasonable for us to say, what can we be in 20 years?
