Bryan Johnson measures his body's biological age organ by organ, finding his left ear at 64 due to childhood hearing damage while his diaphragm is 18. He argues aging can be slowed or reversed, not accepted as inevitable. His goal: prove that living longer and healthier is possible.
He calls himself the world's most measured human. And if you ask him how old he is, well, here's how he explains it so we can say my left ear is 64. Okay, so I have hearing damage as a child. My diaphragm strength is age 18. What's the end goal? To demonstrate that we can dramatically slow the rate of aging and reverse the aging that had happened if we didn't have decay and decline as a assumption that happened. What if it would change everything about being human? I don't have a fear of death. I have a love of life.
