Aging remains a surprisingly mysterious process. A wealth of past scientific research has shown that many bodily and cellular processes change in undesirable ways as we grow older. But science has not been able to establish definitively whether such changes result primarily from the passage of time - in which case they are inevitable for anyone with birthdays - or result at least in part from lifestyle, meaning that they are mutable.
