A man who has spent millions trying to reverse his biological age has revealed how much time he's shaved off.
Bryan Johnson is a 45-year-old tech developer who lives in Venice, California. And he's been working hard to find the secret to eternal youth, or at least he's been trying to gain a few extra years.
Now, while it might seem a pretty bonkers idea, the billionaire has enjoyed a fair bit of success, working with his crack team to help improve his body.

But how does it work? Well, the intensive program, which he's dubbed 'Project Blueprint', sees Bryan put through the mill, testing certain criteria, such as his lung capacity, body fat, and strength, etc.
This is all closely monitored by around 30 doctors, who analyse every part of his body and fitness levels in his bid to turn back the hands of time.
One part of his workout routine that puts his body through the equivalent of 20,000 sit ups in just half an hour.

So yeah, it's not for the faint-hearted.
Speaking to the BBC, however, it seems to be working.
Bryan told the outlet that he has managed to de-age certain parts of his body at a cellular level.
"My left ear is 64, my fitness tests say I'm 18, my heart is 37, my diaphragm strength is 18," he says, admitting that some parts of his body are older than others.

"I playfully say I'm trying to become like, an 18-year-old. My son is 17, so I always tease him and say, 'When I grow younger, I wanna be like you'."
He added: "If we slowed the speed of aging, and even reversed it, it would change what it means to be human."
According to Bloomberg, in order to achieve his goal, Bryan has to undergo numerous medical procedures each month, with the outlet describing some of them as being 'quite extreme and painful'.

In a post published on Medium last year, Johnson opened up about his plans.
"With my world-class team of doctors, researchers and clinicians, if I am able to reverse my measured biological age by 1.01 years for every one year that passes, that is evidence that we have reached the first stage of aging escape velocity where life expectancy increases faster than passed time," he wrote.
"As for the magic pill, it appears that for the foreseeable future, achieving and maintaining peak wellness is just going to be a lot of really hard work."
