For example, healthy cells are damaged over time when our immune systems shift from reacting to short-term problems like injuries and infections to gradually producing chronic inflammation throughout the body. Time also gradually shortens the telomeres that act as protective caps for our DNA-containing chromosomes.  These and other changes make our bodies less and less able to deal with stresses from inside and outside of our body.
