Maximum age a human can live to as biohacker Bryan Johnson announces autoimmune gastritis disease
While biohacker Bryan Johnson may wish to extend his life as long as possible and achieve some form of immortality, science indicates there's really only so long the human body can realistically survive.
48-year-old Johnson has been spending a veritable fortune on attempting to de-age his body, with him injecting himself with his son's blood and setting himself a strict routine he hopes will make him biologically younger.
However, the biohacker recently announced that he's been diagnosed with autoimmune gastritis (AIG), an incurable condition which Johnson describes as his stomach 'eating itself'.
He said: “I just discovered it in May. I'm unsure how long I've had it. AIG causes irreversible damage: nutritional deficiency, anaemia, and over a long horizon, elevated cancer risk.

"When AIG is discovered today, standard medical care concedes defeat, stating that nothing can be done except managing the condition, no matter how awful or lethal the effects.”
The diagnosis may be a reminder to Johnson that for all of his efforts to make his body younger there is always something about biology you can't control, but he's vowed that he's 'going to try and solve it'.
While he wants to cure AIG, something he might never find the cure for is age itself.
With the right lifestyle and luck people can live beyond 100, but research into just how long a human body could theoretically last warns that cells appear to have an absolute maximum of 150 years before they give out completely.
Other studies paint a more pessimistic picture of the theoretical maximum lifespan of humanity, suggesting that we've already just about hit the limit.
The oldest person in recorded history was Frenchwoman Jeanne Calment, who lived to the ripe old age of 122 years and 164 days, but if humanity can't get much further than that many people will fall short in their natural lifespan.
Bryan Johnson’s wildest experiments in his quest to ‘live forever’
De-ageing his penis
While the thought of it may make you wince, Johnson has been putting his manhood through the wringer in the hopes of bringing back his '22-year-old penis'. From semen analysis and blood flow testing to Botox injections and shock wave therapy, he seems to have done it all.
The biohacker claimed to have been able to lower his 'erection age' by over half thanks to this long-winded ritual.
As well as keeping track of his own 'erection data', Johnson has also been controversially comparing the stats to his 19-year-old son's.
Injecting himself with his son’s blood
The biohacker went viral in 2023 after sharing that he'd come together with his then-17-year-old son and his 70-year-old father to take part in what he described as 'the world’s first multigenerational plasma exchange'.
The process saw Johnson have a litre of his blood removed and separated the plasma. He then had the same amount of his son's plasma infused into his veins.
However, after seeing 'no benefits', Johnson announced he was 'no longer injecting my son's blood'.
Instead, he said he 'upgraded' to 'total plasma exchange'.
Psychedelics
Last year, the biohacker documented his trip after taking 5g of magic mushrooms. Afterwards, he admitted he was 'happy to be alive', and the experience had 'changed' him, but 'probably not as you’d expect'.
Johnson also shared the effects of taking 27mg of the 'world’s most powerful' hallucinogenic, 5-MeO-DMT, which left him 'stunned beyond comprehension'.
An extensive morning routine
Johnson recently shared an update on what he does each morning, noting that it takes four hours and 46 minutes.
"My morning routine is always evolving as we update protocols. This is what I'm experimenting with right now," he writes on his website.
