“I’m potentially the most measured person in human history."

Joining HowTheLightGetsIn from California, Bryan Johnson is a entrepreneur and venture capitalist turned self-declared immortality pioneer. The founder of payments company Braintree, sold to PayPal for $800 million in 2013, Johnson has spent his fortune on a stranger and more audacious project than anything Silicon Valley has seen: attempting to reverse his own biological age, and persuading the rest of humanity to follow him.

Project Blueprint, his $2 million-a-year regimen of diet, supplements, and experimental therapies, has made Johnson the world's most documented human guinea pig. He wakes at 4:30am, takes approximately 100 pills daily, submits every measurable system of his body to algorithmic optimisation, and broadcasts every biomarker to his millions of followers. His physicians claim the data shows measurable age reversal. His book Don't Die and We the People explore the new frontiers of being human.
