Rejuvenation Olympics competition heating up

What is it: Rejuvenation Olympics, a website that tracks the performance of various "rejuvenation athletes." Rejuvenation Olympics was created by Bryan Johnson, the Silicon Valley exec turned longevity enthusiast, as a way of dramatizing and popularizing the field of longevity.

How does it work? Anybody can participate in the Rejuvenation Olympics by getting the DunedinPACE test performed by TruDiagnostic, a third-party lab that performs biological age tests.

The results then go up on the Rejuvenation Olympics website, which tracks the top 20 relative and absolute rejuvenation performers.

Why should we care: Interest in the field of longevity is heating up, and Johnson's various efforts are a significant part of that.

Beyond the public exposure that Rejuvenation Olympics creates, there's the actual information — insights into which interventions and which longevity labs are producing the most meaningful impacts in a head-to-head comparison.

And the news is: There has been movement in the Rejuvenation Olympics results. So far, 1750 people have participated, including Johnson himself — via a rejuvenation regimen that's costing him $2 million per year.

The surprising result is that Johnson has now fallen out of the top five. That's good news for the rest of us, who are interested in longevity but don't have $2 million a year to spare for it.
