In this video, Brian Johnson discusses his blueprint effort, which aims to use an algorithm to take better care of him than he can himself. He explains how he hired a team of 30 doctors to create a systematic protocol to achieve optimal health by measuring all his organs, generating hundreds of data markers, and repeating the protocol. Johnson also discusses the three principles of the blueprint effort: goal alignment, autonomous self, and zero principle. He believes that technology can be used to improve human well-being and that the relationship we have with technology should be reversed, with technology in service of human well-being. Johnson also talks about the rejuvenation Olympics, where people compete to improve their health, and how he is excited to see data that the blueprint works in other people's lives.
