The man known as the 'ultimate biohacker' has spoken about his goal of 'immortality' through various extreme methods.
Bryan Johnson has previously given us an insight into his five-hour 'longevity routine', which he does every day and includes exercise, a number of therapies, and supplements.
Johnson claims he spends about $2 million (£1.4 million) every year to 'stay young' forever, as he's gone as far as injecting himself with his teenage son's blood.
The American leaves no stone unturned when it comes to his progress, revealing that he can get erections similar to an 18-year-old and made some comparisons to his son's manhood.

Now, he has claimed that he is a decade younger biologically due to all the work he puts into biohacking, taking to X to explain his goals.

Johnson, who has openly admitted he's used magic mushrooms as part of his journey, said that he remains 'the same biological age' as 'one year of time passes'.
He added that 'for the first time in the history of life on Earth, in just the past 24 months, the window has opened for a conscious being to realistically strive' for immortality.
The dad said that he hopes to achieve the goal within the next 15 years, explaining: "We currently do not know how 2039 immortality will be achieved. There are new, promising therapies that can turn back the clock decades, but they’re buggy. Sometimes they mistakenly cause cancer. We gotta fix that.
"But we know immortality is possible because nature has already solved it. This isn’t a physics problem like trying to travel faster than the speed of light, it’s a biological engineering problem that evolution has cracked multiple times."
Johnson spoke about 2039 being a 'reasonable target' due to the contribution of AI to innovating technology and methods, which can be used to 'speed things up dramatically'.
"This is what I’ve been doing for six years," he said of biohacking, adding: "As crude as longevity technology is today, the improvements I’ve personally seen are stunning."

Johnson added: "I started as a worn-down, inflamed, aged 42-year-old who’d broken himself on the rocks of American food slop and entrepreneurship martyrdom. Six years later, my body largely operates at elite 18-year-old levels. That includes my cardiovascular system, fertility, strength, and hormones."
He said that some animals are 'effectively ageless' and 'immortal' on their own, suggesting that it is possible for humans to do the same.
"We could do so much more and faster if we had better measurement and better therapies. Both of which are cooking all over the world right now," Johnson noted.
The 48-year-old further claimed that he has 'thousands of Bryan Johnson organ clones built in a dish' to test the effects of drugs and biohacking methods on how his body ages.
He said that immortality is 'the coolest goal imaginable', claiming that society and companies are affecting out life expectancy.
Johnson explained: "Right now, we are a suicidal species. We do all kinds of really primitive s***. We unnecessarily kill ourselves with what we eat and how we live our lives.
"Companies make profits from killing other people with their products. We trash the only home we have. We celebrate these things as virtue. It’s really f***** up and backward."
