Julie Gibson Clark is aging at 0.665 of a year for every chronological year she lives. So while the Phoenix-based single mother is 55 years old, her “biological” age, which may determine health span and life span more accurately, is decreasing—that is, according to her latest epigenetic DNA test, evaluating how her lifestyle influences her genes.
Amid the craze to live forever—a $26 billion business predicted to nearly double in the next decade—Clark’s results are more than impressive. In a global online longevity game called the Rejuvenation Olympics, ranking 4,000 people’s pace-of-aging averages across six months, Clark is in second place. She ranks higher than No. 6 Bryan Johnson, the wealthy tech founder who spends $2 million per year on reverse aging, and No. 19 Peter Diamandis, whose venture fund has put $500 million into growing technologies, many of which are aimed at research and development for healthy aging and extending life span, according to his website.
