People have been obsessed with the idea of staying young for millennia.The ancient Mesopotamian hero Gilgamesh went hunting for a way to achieve eternal youth. Loki was sent to retrieve Idunn and her golden apples. In more concrete history, early Spanish explorers went hunting for the Fountain of Youth in Florida. People want to be young and healthy. They have, however, consistently confused the concepts of getting older and growing old. Getting older is more or less inevitable. As each year passes, you get a bit older.
