What if our body could stay in its prime forever? What if we could be biologically immortal like a hydra—a tiny freshwater creature that can continuously renew its cells? Or what if we could turn back the clock like some jellyfish that never die but revert to an earlier form and go through life all over again?

But most cells in our body aren’t built to last a lifetime: they’re damaged all the time by everything from ultraviolet rays to poor nutrition. When this happens, cells make copies of their chromosomes, which contain our DNA, and divide into healthy new cells.

But at some point, cells lose their ability to replicate.

After completing Blue’s exam, Dr. Linnehan and her colleagues trudged back up the hill to their offices, the chatter of dolphins and sea lions fading behind them. But even indoors, it was impossible to escape the animals’ presence: There were photos of dolphins, dolphin cartoons and a plushy toy sea lion. Anatomical models of dolphins sat on numerous desks.

The laboratory, located just a short walk away, is typically bustling after the animals’ morning medical checks, as technicians process any recently collected blood, urine, fecal or other samples. Later, the samples are stored in a small, windowless room across the str…….

45-year-old Bryan Johnson is dedicated to living longer. And by longer, I mean far outpacing the rest of us by reversing the natural process of aging. He’s already biologically at least five years younger than his age, according to his team of doctors. 

The mega rich California CEO follows a strict diet, sleep wind down ritual, exercise regimen, takes a round of daily supplements, and undergoes countless medical tests as he strives for the biological age of 18. Johnson is estimated to spend over $2 million this year on medical tests and various procedures aimed to help him achieve his goal, according to a profile of his endeavors in Bloomberg.
