Billionaire biohacker Bryan Johnson has revealed that his nighttime erections now last longer than epic movies like Titanic and Lord of the Rings, calling the feat a key longevity biomarker.
In an Instagram post, Johnson shared his 'personal best' for nighttime erection duration, stating it now exceeds four hours. He explained why this is significant for his health as part of his multimillion-dollar project to combat ageing.
Johnson's health routine and measurements
As part of his project, Johnson goes to bed at 8pm wearing a tiny Bluetooth-powered jet pack to measure his nighttime penis activity. His partner, Kate Tolo, also undergoes testing, using an acrylic vaginal 'techno-tampon' to measure her period blood flow, which Johnson calls 'lady boners'.
Johnson, 49, claimed his nightly erections are growing stronger despite his age. He wrote: "Breaking news.... My boners are now longer than 4hrs."
Longevity claims and social media reaction
Johnson described nighttime erections (NTE) as "a tier 1 longevity biomarker as critical to systemic health as VO2 max, resting heart rate, HRV, and blood pressure." He added: "Women have them nightly too."
He shared that his best nightly erection over the last 18 months lasted 4 hours and 2 minutes, which he said is longer than Titanic and Lord of the Rings (extended edition). Johnson also noted he takes 5 mg of Tadalafil daily, which he says may add about 20 minutes to total nighttime erections.
Johnson stated: "To be 49 years old and be in the 99th percentile of 20 year olds (4 hr+) requires pristine sleep performance, endothelial responsiveness, and nervous system capacity." He encouraged men to monitor their NTEs, calling them an early warning signal for microvasculature dysfunction.
Social media users reacted with confusion and humor. One wrote: "Weird flex, but okay." Another said: "Bryan bragging about his Johnson." A third commented: "Tracking boner time is a new level of hardcore." A final user joked: "I wake up hard asf everyday thanks for the reassurance."
Johnson previously claimed that if aliens examined him, they would struggle to distinguish his erection function from his teenage son's. He said: "In many ways, I am 18. If an alien encountered me, they’d struggle to distinguish me from my son."
