When asked to estimate a three minute period of time, 20 year olds are significantly more accurate than the middle aged or elderly. Why? It seems that the elderly experience time more quickly than the young. Remember when you were a child and the summer holidays seemed to last forever? Perhaps as you get older, the reverse is true and the summer passes in what seems like a single month.
