Tech bros like Bryan Johnson are spending millions to shoot for immortality. These women are besting them in the longevity game—but don’t call them ‘biohackers’

Julie Gibson Clark doesn’t use expensive medical treatments, gadgets, or a team of scientists to “biohack” her age. She sticks to a vegetable-rich diet, exercises, and meditates. Her biggest health expenditures are a $27-a-month gym membership and a $79-a-month supplement subscription. 

So the 55-year-old single mom in Phoenix was surprised to learn she ranks at No. 2 on the worldwide leaderboard of an online competitive longevity game, the Rejuvenation Olympics, which tracks and ranks about 4,000 participants’ pace of what’s sometimes called “biological” aging. It’s based on epigenetic DNA tests—which give an insight into how environment and lifestyle can influence how people’s genes work. Clark ages at 0.665 of a year for every additional chronological year, according to her most recent test, which takes into account the average of participants’ pace of aging scores after six months or more.
