A live-stream broadcast of China’s military parade has captured Xi Jinping and Vladimir Putin discussing biotechnology’s potential to extend life.
An interpreter translating Mr Putin can be heard saying in Mandarin that human organ transplants could let “us live younger and younger, and perhaps even achieve immortality”.
Mr Xi responded that it may be possible for people to live to 150 years this century.
Liver is a weird one. The liver is one of the only organs that can regenerate. Anyone can donate a chunk of their liver. It just regrows after awhile, as well as in the recipient. So livers are better at staying under the radar from the immune system.
