Billionaire Anti-Aging Zealot Shares Son’s Erection Data in Bizarre Post

Bryan Johnson, the eccentric tech mogul obsessed with trying to live forever via an elaborate anti-aging regimen, is talking about his penis again—and this time roping in his 19-year-old son.

In a bizarre post on Wednesday night, Johnson, 47, posted his “nighttime erection data”—a comprehensive dataset that includes the number of erections, total length of his “episodes,” his sleep efficiency, and something labeled “erection quality.”

He then compared his data to the same statistics measured on his 19-year-old son, Talmadge.

“His duration is two minutes longer than mine,” Johnson wrote. “Raise children to stand tall, be firm, and be upright.”

Although Johnson’s post was met with incredulity from other users on X, Talmadge appears to be fully on board with this aspect of his father’s “Don’t Die” philosophy. “I’m grateful for the way my dad has raised me,” he wrote after reposting the data.

Johnson’s close relationship with his son, who he has previously received blood transfusions from as part of his anti-aging efforts, was part of the focus in a recent Netflix documentary featuring the multimillionaire.

It’s not the first time Johnson, the founder and former CEO of the company that once owned Venmo, has shared extensive data about his penis health. Johnson recently broached the same topic in a December blog post, where he claimed that for men, “if you’re not having robust boners at night, you’re 70% more likely to die prematurely. If you’re grinding at the expense of your health, you’re flaccid.”

It was not immediately clear where he got this data from, however, standard erectile dysfunction has long been linked to an increased cardiovascular risk. The condition greatly increases the risk of an early death by at least 25%, according to studies analyzed by the National Institutes of Health.

In the same post, Johnson compared nighttime erections to “how your penis works out,” by stimulating blood flow to the sex organ. He also went into detail on the statistics he keeps, which are measured by regular sperm counts, ultrasounds to measure “penile blood flow,” and measuring the size of his prostate, among other inputs.

Previously, Johnson has also gone in-depth on his “penis rejuvenation” strategies, including weekly penis injections that he rated up to a “9.5 out of 10” on a painfulness scale.
