"I’m going to try and achieve immortality by 2039," biohacker Bryan Johnson said as he's been setting out his plans to 'live forever'.
The Silicon Valley entrepreneur, famous for extreme longevity experiments, believes science, biology and AI are finally lining up to make eternal life achievable.
He shared all 909 words with his followers, opening with a confident declaration: "One year of time passes and I remain the same biological age. I invite you to join me."
He framed his mission as humanity’s oldest obsession, arguing that the 'fountain of youth' has always been out of reach - until now.

According to the 48-year-old, the last two years have changed everything: "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 this goal."
He described the day as an 'absolutely insane moment'.
While he admitted there’s no step-by-step guide to immortality yet, Johnson insisted the evidence already exists in nature.
"We currently do not know how 2039 immortality will be achieved," he said.
"But we know immortality is possible because nature has already solved it."
Okay, it's a bit of a stretch, but he pointed to creatures like the freshwater hydra, which doesn’t age, and the so-called immortal jellyfish, which can reset its life cycle. Lobsters, he notes, also maintain their DNA through highly active telomerase... in his words: "We need to port the software to humans."
Johnson believes artificial intelligence is the key to all this, claiming that '2039 is a reasonable target because of the accelerated, AI-driven rate of innovation'.
He continued: "AI is morphing from assistant to scientist."
Combined with advanced biomarker tracking, he says this creates a feedback loop that dramatically speeds up progress.
Johnson claims his own body is proof of concept. After six years of obsessive measurement and protocols, he says his cardiovascular health, strength, fertility and hormones operate at 'elite 18-year-old levels'. Still, he admits not everything is reversible, noting mild to moderate hearing loss and a brain that remains biologically 42.
Incredibly, Johnson revealed he’s having 'thousands of Bryan Johnson organ clones built in a dish' to safely test drugs and therapies before trying them on himself.
Whether immortality is achievable or not, Johnson is clear on one thing: he thinks it’s 'the coolest goal imaginable' - and he’s betting his life on it.
