He's one of the most divisive figures in health tech, but you've got to hand it to Bryan Johnson, he really looks like he knows what he's doing. The biohacker has done it all in his quest to 'live forever', from jabbing himself with plasma injections from his son to having his frozen body flown 3,750 miles.
While anyone (who has the money) can spend $2 million a year to overhaul their life, you've got to admit that Johnson looks completely different to the way he did before. He's sat down with the likes of UFC's Dana White and Logan Paul, while he's recently headlined Netflix's Don't Die: The Man Who Wants to Live Forever.
Still, his controversial methods continue to baffle the world, just like when he shared his son's 'erection data' on social media. Yes, you read that right.

Even if Talmage Johnson doesn't mind his dad letting the world know how many times a night he gets it up, others continue to question the biohacker's methods.
Now, he's encouraging men to check their own 'Johnson' in a bid for them to also hack their own body clock.
Over on his Project Blueprint site, Johnson explains how his quest to de-age his body involves regular penis checks. He starts by warning readers that if you aren't having 'robust boners', you're 70% more likely to die prematurely. Johnson also says that while there isn't much data on women, they should also monitor their nocturnal arousal cycles.
Looking at the data, Johnson suggests that 'healthy' men in their twenties can experience over three hours of nighttime erections that occur in three to five erection episodes. It dips to less than 50 minutes for those over the age of 75.
Johnson claims that erection problems can show up as early as five years before heart disease, so it's something to look out for.
He also says that men should abide by the motto of 'use it or lose it', suggesting that men should think of nighttime erections as a penis workout, and without 'regular exercise', scar tissue can develop. Erections are apparently important because they keep tissue healthy by bringing in oxygen-rich blood.
In terms of how he tests his penis health, the intensive regime involves semen analysis, urine and blood flow testing, examining prostate health, taking questionnaires about his sexual function, prioritizing 'core health practices' like sleep and exercise, and measuring his nighttime erections.
He then says you can get your AndroAge (erection health age) score by using the AdamHealth sensor. It might just be a plug to AdamHealth, but Johnson is clearly having an effect. The AdamHealth site currently has the following statement: "Due to overwhelming demand, the Adam Sensor is currently on a waiting list. All orders will ship within 7-8 weeks from the date of purchase."
As for Johnson, he seems pretty happy with his nighttime erection data, boasting that he's pitching a tent for around 3 hours and 14 minutes a night.
