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

Johnson, the founder of Kernel, OS Fund, and Braintree, compared his data to the same statistics measured on his 19-year-old son, Talmadge (left).

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

Talmadge appears to be fully on board with this aspect of his father’s “Don’t Die” philosophy. “I’m grateful for how my dad has raised me,” he wrote after reposting the data.

For those who don’t remember, Johnson has previously received blood transfusions from his son as part of his anti-ageing efforts. A recent Netflix documentary featuring the billionaire focused on this.

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 son’s health.
