Wishful thinking is a temptation, but it doesn't lead to reasonable analysis. Xi is in fine health at the age of 66. His father lived to the ripe age of 88. His mother is still alive, at 93. We can expect him to receive better medical care than they did, since he is leader of China and they spent several decades getting purged, imprisoned, overworked, and starved by the party. If the Chinese people look for a change in leadership, they had best look somewhere besides the calendar.
Imagine that we lived in a world where new technology is developed all the time, although not everyone gets access to all new technology simultaneously. In such a world, wouldn't it be possible for the powerful dictator of the most populous and technologically advanced nation in that world to receive seemingly miraculous life-extension treatments before most people knew of their existence?
