The panellists are asked "How old are you?" The official answer is it depends on which part of the body it is. Red blood cells regenerate every 120 days, your liver regenerates every 300-500 days, so roughly 1½ years and the entire human skeleton is replaced every 10 years, although the process makes the bones age. So, the entire body is roughly 7-10 years old, but some of the cells are younger than that. 98% of the 7 billion billion billion atoms in the human body are replaced yearly. Most of the cells in your body aren't even human, they're bacteria. There are 50 species of bacteria in the human body, more than 10 times the number of human cells.
