Tech Billionaire Spends Millions Trying to Defeat Death Through Health Tracking and Blood Infusions

Tech billionaire Bryan Johnson spends millions on anti-aging experiments like monitoring health data, taking supplements, and infusing his son's blood.

Johnson believes going to bed early, exercising, and avoiding harmful things are key to health.

He says stopping addictive behaviors may be more powerful than starting healthy ones.

Johnson thinks humans are unlikely to survive without AI's help.

He believes defeating death, not conquering territory, should be humanity's focus in the 21st century.
