Tech entrepreneur Bryan Johnson shares experience with controversial fat injections for anti-aging efforts

Tech entrepreneur Bryan Johnson, 47, has undergone controversial fat injections as part of his anti-aging efforts. The procedure resulted in severe swelling and temporary vision loss due to an allergic reaction, prompting him to share his experience on social media. Johnson, who follows a strict regimen to maintain a youthful biological age, had to use fat from another person after finding he lacked enough of his own. He reported that his face returned to normal after a week and plans to continue his experiments. His "Project Blueprint" includes a vegan diet, numerous supplements, and extensive health monitoring. Johnson aims to demonstrate that it is possible to significantly reduce the biological age of human organs.
