It is Wednesday in Los Angeles. The air is balmy, the Dodgers have a home game, and tech mogul Bryan Johnson is preparing for his fifth penis injection in 10 days. In other words: business as usual.
Johnson, 45, has the chiseled, taut body of a teenager, which he has earned through a punishing fitness and diet regimen and constant medical intervention. His objective, he says, is clinical, not aesthetic: to optimize the human body for performance and longevity.
“We take an organ by organ approach in doing this…whether it’s the heart or the lungs or the liver, and of course, the male reproductive system.”
