Bryan Johnson, a millionaire tech mogul known for his extreme anti-aging techniques, is once again raising eyebrows.
On Wednesday, Jan. 22, the 47-year-old biohacker took to X to share his teenage son’s “nighttime erection data.” Bryan posted side-by-side charts that compared his and 19-year-old Talmage Johnson’s sleep efficiency, number of nightly erections, average erection quality, and average erection duration.
“His duration is two minutes longer than mine,” Bryan wrote on X. “Raise children to stand tall, be firm, and be upright.”
Talmage reshared the charts on his X account and expressed gratitude toward his dad.
“I’m grateful for the way my dad has raised me,” he wrote.
Although Talmage had no problem with his father’s post, dozens of X users sure did. In the hours since releasing the “erection data,” Bryan has been relentlessly hit with criticism, questions, and unsavory labels.
This isn’t the first controversy Bryan has faced in recent years. Back in 2023, the entrepreneur made headlines for his unusual — and quite pricey — attempts to slow down the aging process.
According to Bloomberg, one of those techniques involved “a tri-generational” blood swap with his then-70-year-old dad, Richard Bryan, and his then-17-year-old son, Talmage. Bryan reportedly conducted the plasma exchange after getting approval from his team of 30 doctors. He said he hoped the exchange would stall age-related brain decline, but ultimately discontinued the therapy after no benefits were detected.
“Young plasma exchange may be beneficial for biologically older populations or certain conditions,” he wrote on X in 2023. “Does not in my case stack benefit on top of my existing interventions. Alternative methods of plasma exchange or young plasma fractions hold promise.”
Bryan was also the subject of Don’t Die: The Man Who Wants to Live Forever, a newly released Netflix documentary that explored his radical quest to extend his life. This included everything from his plant-based diet and intensive workout regimen to his strict sleeping schedule and, yes, regular boner monitoring. Bryan addressed the latter in a 2023 interview with Indy100, explaining how erections are a strong indicator of good health.
At the time of the interview, Bryan revealed he was erect for “two hours and 12 minutes” a night on average and wanted to extend that time to three hours and three minutes, which is reportedly average for an 18-year-old. So, how did he attempt to “rebuild” his erection? Through shockwave therapy.
“So there’s this technology, you have a wand and you sit in a chair and then the technician uses the wand and basically shocks your penis, through the acoustic technology. “And it does the same things as workouts [...] where you’re creating micro injuries so that it rebuilds.”
