Inside Bryan Johnson’s Private Longevity Night: Baseline Tests and a Push for Longer Life

A Business Insider reporter attends Baseten’s private Longevity Night in San Francisco, where attendees undergo face-age scans and a series of bioage tests (grip strength, push-ups, one-leg stand), breathwork, and a chef-guided dinner, while Bryan Johnson and his team encourage more effort. The event is framed as baseline measurements rather than verdicts, highlighting Silicon Valley’s appetite for shortcuts to longer life and the tension between aspirational wellness culture and pragmatic health messaging.
