Biohacker Bryan Johnson and Partner Kate Tolo Push Longevity Research Amid Criticism
Millionaire biohacker Bryan Johnson and his Australian partner Kate Tolo say they remain focused on anti-aging work, shifting attention to women’s health despite public backlash.
Bryan Johnson, a Silicon Valley entrepreneur known for extreme anti-aging projects, celebrated his 49th birthday while asserting he feels younger than his partner, Kate Tolo, who is 30. During an interview with Triple J Hack, the duo acknowledged a sizable portion of the public hopes they fail, yet they remain committed to their "Don't Die" mission, now emphasizing women’s health. Tolo, originally from Mackay, has become co-founder of Johnson’s brands Blueprint, Don't Die and Immortals, and is tracking millions of data points on her menstrual cycle and other bodily metrics.
Their recent claim of creating a cloned newborn was clarified as the generation of induced pluripotent stem cells, a technique scientists find promising but distinct from true cloning. Medical expert Brooke Nickel expressed caution, noting the lack of robust evidence behind many biohacking claims and the risk of conflating them with legitimate health practices. Johnson and Tolo reject suggestions that they are monetising fear, insisting their work aims to solve incurable diseases and advance longevity for all.
