Sam Altman has returned to his position as CEO of OpenAI after a few chaotic days at the company. He is one of many tech leaders obsessed with extending lifespan. He is also said to have prepared for worst-case scenarios such as the spread of a deadly virus, nuclear war, AI attacks, etc., with stockpiles of guns, gold, and survival supplies. Whether eating, working, or resting, he pays particular attention to the daily aspects and maximizes efficiency.

Below is Altman's daily schedule, as revealed by himself.

Altman drinks a large espresso in the morning right after waking up but rarely eats breakfast. He says he typically fasts for 15 hours a day. When reading emails, he uses a full-spectrum LED light for about 10-15 minutes. He also avoids early morning meetings because that's when he's most productive.
