Bryan Johnson opened his talk by leading the audience through biological age tests: a one-legged balance test with eyes closed, a sit-and-reach flexibility test, and a reaction time test, explaining how each maps to a biological age range. He said he has become the most measured person in human history, gathering 1.5 billion data points on his body, and that he found severe hearing damage in his left ear from past gun use and loud music, which he addressed with hearing aids. Johnson argued that managing resting heart rate before bed is the single most important health practice, recommending a final meal four hours before bed, screens off 30 to 60 minutes before sleep, no caffeine after noon, amber and red lighting at home, and a nightly wind-down routine where he personifies his thoughts as 'Bryans' to reconcile anxiety. He framed his Don't Die project as fundamentally about AI alignment, asserting that existence is the highest virtue and that society's focus on power, wealth, and status is killing people. He predicted lifespan extension could accelerate past one year per birthday, potentially reaching 110, 120, or 140 years, and that future technologies will make current pro-death arguments seem crazy. He encouraged prioritizing personal well-being over martyrdom and said women gain an extra year of life per child.
