Millionaire Bryan Johnson slammed over ‘penis contest’ with teen son

A tech millionaire famed for undertaking wild experiments in a bid to “not die” has published “intimate” details about his son.

An American tech-mogul turned anti-ageing fanatic who has spent millions trying “not to die” has been criticised after sharing data about his teenage son’s night-time erections.

Bryan Johnson has amassed a huge following after he sold his eCommerce payments company and began documenting his quest to uncover the secret to longevity.

The 47-year-old completely overhauled his lifestyle, introducing a strict diet that stops him eating food after 11am, and began putting his body through an array of wild experiments, including blood-plasma donations from his teenage son.

His unorthodox approach to achieving optimum health often sees him going viral, not always for the right reasons, and has also seen him become the star of a new Netflix doco titled Don’t Die.

But recently, he appears to have gone “too far” with fans, after sharing the results of an overnight erection-tracking machine for both himself and his son Talmage, 19.

“His duration is two minutes longer than mine,” Johnson wrote in the post on X.

“Raise children to stand tall, be firm, and be upright.”

The data he posted included the number of erections, average duration, average quality and overall sleep efficiency the pair have, though Mr Johnson didn’t disclose why he was obtaining the information.

Many have been quick to question why a father would want to know such information about his son, with some reacting with shock and disgust.

“For the love of God, why would you post this on the internet publicly? I feel bad for your son,” one user wrote on X.

“I have a feeling this won’t even crack the top 10 most disturbing chapters in your son’s inevitable autobiography,” another user wrote.

As another stressed: “Still time to delete this.”

Another sarcastically quipped: “Don’t listen to the haters Bryan. Knowing the details of your son’s erections is perfectly normal, and, quite frankly, it would be weirder if you didn’t post about it.”

Others said it was a “weird” and “gross” thing to share, asking how the data was even obtained.

“My iWatch doesn’t tell me this, it must be broken,” joked one.

“I don’t even want to know how you measure this,” remarked another.

Meanwhile one quizzed: “How is the quality of an erection evaluated?”

One social media commenter pointed out it the post felt like “a penis measuring content”, adding it was extremely “intimate” information to share with millions.

It’s not the first time Mr Johnson has faced controversy over his unusual health experiments – which he reportedly spends $2 million (about $A3.1 million) on every year.

The self-described “biohacker”, who made $US800 million ($A1.3 billion) when he sold Braintree Payment Solutions to eBay in 2013, was criticised when he injected a “donor’s” fat into his face to attain a more youthful look and it went horribly wrong.

“I got really lean and lost a lot of fat—especially in my face. My biomarkers were improving, but I looked gaunt,” he wrote on Instagram at the time.

“People thought I was on the brink of death. Facial fat, we discovered, is pretty important for how people perceive youth.

“It didn’t matter how good my biomarkers were if I didn’t have face fat.”

But his attempt to restore “youth” back to his face took a disastrous turn after he injected fat from a donor – used because he didn’t have any fat of his own – and it caused his “face to blow up”.

Many were furious at the stunt, which many suggested was “dangerous”, and condemned him for sharing it publicly.

“Dear oh dear!! This is what happens when someone has more money than sense,” one wrote.

“This sends a terrible message about the privilege of growing older. Shame on you,” another said.

However, not everything he’s shared has been rubbished, with some doctors embracing Mr Johnson’s claims “junk food is cancer”.

“As a doctor, I couldn’t help but lean in to hear his take – because, believe it or not, he’s onto something,” Sydney practitioner Dr Zac Turner wrote in his news.com.au column.

“Junk food isn’t just a guilty pleasure, it’s a carefully engineered product designed to make us want more, often at the expense of our health.”

However, Dr Turner stressed “junk food itself isn’t a direct cause of cancer, it plays a significant role in creating the conditions for it to develop”.
