This Is What Makes You Age

2 months ago

Your body is made up of around 100 million million cells. Some of them, including brain cells, are rarely replaced. Others are constantly replaced, as existing cells multiply to make new ones.
However, each cell can only multiply a certain number of times before it dies. As more cells are lost or damaged, you start to show signs of ageing. For example, the fewer skin cells you have, the thinner your skin becomes.
