He's 45, Plans to Live Another 135 Years. Here's How

Dave Asprey is 45, which in his view "officially" makes him a young adult. That's because his well-known goal is to live to 180; he's now a quarter of the way there. In a lengthy piece for Men's Health, Rachel Monroe digs into the Bulletproof Coffee (that's coffee with oil and butter in it) founder's quest—which he thus far says has cost him $1 million—its origins, and whether it's brilliant or BS. Asprey doesn't have a medical degree (his background is in tech), and he got into biohacking via trial and error. He says he tipped the scales at 300 pounds in college and suffered from ailments ranging from chronic strep throat to attention deficit disorder. He started logging 90 minutes of exercise and eating 1,800 calories or fewer. "I could max out every machine but two at the gym," he says, but his weight didn't budge. Doctors offered no useful advice.

So "Asprey decided to experiment on himself," writes Monroe, and he tested a low-carb diet. He shed 50 pounds. He started taking "smart drugs" ordered from Europe, began downing supplements (he currently takes 100 per day), concluded kale could be toxic, and launched Bulletproof, which has now gotten more than $50 million in funding. His quest for longevity has led him to "extreme interventions," among them what he says is "the most extensive stem-cell treatment that's ever been done on a person at one time": Half a liter of bone marrow was taken from his body, the stem cells were removed, and then they were injected into his joints, spinal cord, scalp, face, and male organs. He plans to do it twice a year. Read the full story, which digs into more of Asprey's assertions and why he's found a captive audience, here. (More bulletproof stories.)
