If you've seen that 7-year comparison chart and are curious about the face that is firm yet has a 'mechanical feel,' you must get to know Bryan Johnson — a Silicon Valley billionaire who fights aging with a programmer's logic, known for treating carbon-based life as an 'open-source project.'

From startup elite to 'human experimenter'

Starting from scratch, he founded the payment company Braintree in 2007, later acquired Venmo, and sold it to PayPal for $800 million, ultimately amassing a fortune of $5 billion. However, the late nights, stress, and binge eating during his startup phase took a toll on his body. By the age of 43, his heart age was already 60, and he had once come close to taking his own life due to depression. This physical and mental crisis became a turning point, and in 2021, he launched the 'Blueprint Project,' completely transforming himself into an 'anti-aging experimental subject.'

Reconstructing the physical body with 'coding thinking': extreme data-driven and execution power

His core logic is 'let the organs speak, let the brain be quiet,' breaking the body down into monitorable and optimizable metrics, fixing 'bugs' like iterating code:

• Hardware monitoring: He established a 30-person medical team to track the status of 78 organs in real-time, monitoring everything from hair follicle health and frequency of erections to heart function and telomere length, with over 200 biomarkers monitored daily. His small intestine capsule examination alone captured over 30,000 images of the digestive tract, with sleep needing to be precise to 8 hours and 34 minutes.

• System optimization: He strictly consumes 1,977 calories of vegetarian food daily, takes over 140 supplements, performs 67 minutes of exercise consisting of 25 movements, trains with high intensity three times a week, and absolutely does not eat after 5 PM. To resist temptation, he plans ahead to avoid all 'risk scenarios,' stating, 'I won’t let myself see beer and donuts.'

• Extreme debugging: From plasma exchanges among three generations with his 17-year-old son and 70-year-old father to traveling to legally lenient islands to try unverified gene therapies, and even live streaming the consumption of high doses of psychedelic mushrooms in 2025, monitoring neural changes with brain-machine interfaces, each operation is accompanied by hundreds of indicators for tracking.

Controversial 'reverse aging' results and business landscape

According to the data he published, at 48 years old, his heart age is 37, and his skin age is 28, with lung capacity comparable to that of an 18-year-old.
