HOW OLD ARE YOU REALLY? THE BIOLOGICAL METHOD OR ARE YOU "WEARING OUT" TOO SOON?
Now we come to the true method of determining just how old we really are. While the calendar measures the actual number of years we have lived and the mirror reflects how we look, and the milestones, candles and yearbooks give us clues as to how we have changed, longevity scientists have devised another more exciting and more exact way to measure our true age. Is our body older or younger than the calendar? Is it older or younger than the mirror shows? Is it older or younger than all the milestones, candles and yearbooks measure? You'll soon see for yourself.
THE THREE AGES OF MAN

PSYCHOLOGICAL AGE—how old you feel you are.
