I have a new column this week on OnlySky. It’s about the human desire for immortality, as embodied in one man’s obsession.
Bryan Johnson, an ex-Mormon entrepreneur turned biohacker, believes we’re on the brink of inventing medical technologies that will halt or reverse aging. To ensure he stays alive until that day comes, he’s living by a strict diet, exercise and sleep protocol he invented himself. The benefits of those practices are hard to argue with, but he’s not stopping there. In a bid to bring the advent of immortality that much closer, he’s using his own wealth to fund a bewildering variety of medical treatments – from blood transfusions to genetic engineering – which he’s willingly testing on himself as the guinea pig.
Is there any scientific validity to any of this? Is Johnson advancing the cause of anti-aging research, or just making himself a laughingstock for no discernible benefit? Or, worse, is he putting his own health at risk in the service of a foolhardy quest?
Read the excerpt below, then click through to see the full piece. This column is free to read, but members of OnlySky also get special benefits, like member-only posts and a subscriber newsletter:
The base of Johnson’s protocol is a strict diet, sleep and exercise regimen which he follows with religious exactitude, like a medieval monk who abides by a book of hours.
He wakes up at 4:30 AM and completes a vigorous hour-long exercise routine. He eats a vegan diet (the same meals at the same times every day, with barely any variation), consuming his last meal of the day at 11 AM. He avoids alcohol, caffeine and other recreational drugs. He goes to sleep promptly at 8:30 PM every night.
He undergoes a battery of regular medical tests and measurements—from weight and body composition, to grip strength and VO2 max, to regular MRIs and blood tests—aimed at assessing his overall health and gauging his biological age, as opposed to his chronological age.
Johnson’s intention is to buy time through a stepping-stone method (and I do mean buy; reportedly, he spends $2 million a year on all of these treatments). Even if none of the therapies he’s currently using will prolong his life indefinitely, the idea is that they’ll extend it enough that other, more effective anti-aging therapies will be invented in his lifetime, which he can use to extend his life still further, and so on.
