What are the Rejuvenation Olympics?

The "Rejuvenation Olympics" is an informal competition focused on decreasing one's biological age compared to their chronological age. Participants upload their results to track improvements over time. The concept was created by Brian Johnson and features a leaderboard, with individuals ranked based on the difference between their chronological and biological ages. The event's tagline humorously states that you "win by never crossing the finish line," signifying ongoing longevity efforts rather than a definitive endpoint 1.
