Johnson spends millions every year in order to find a way to make his organs similar to that of an 18-year-old male. A tech billionaire on a quest to reverse the aging process believes that it is unlikely humanity will survive without the assistance of artificial intelligence (AI). Bryan Johnson, a 46-year-old tech entrepreneur, spends millions yearly on a team of experts monitoring his health and conducting experiments. The goal: Get his organs to look and act like that of an 18-year-old. Some of his regiments include a strict bedtime of 8:30 p.m., taking 111 pills daily, collecting his stool samples, and having a small device attached to his penis to monitor nighttime erections.
