So far, Chris has done everything possible to delay the aging process. Now he’s facing his most extreme and emotional challenge: three days in a retirement village while wearing an aging suit that turns the simplest activity into a Herculean task. He’s testing the theory that the best way to combat aging and fear of mortality might not be to fight it but accept it.

As Chris bulks up for “Thor: Love and Thunder,” he needs to build a body that looks right for an immortal god. But, he also wants the kind of muscles that are scientifically proven to help him stay strong and healthy as he grows older in real life.

Chris turns to longevity doctor Peter Attia to find out how changing his eating habits can help his quest for longevity. Ironically, the answer is to eat no food at all for four long days.
