WHY DOES TIME GO FASTER AS WE GET OLDER?

A single summer may seem to last for an incredibly long time to a child, whereas for an adult the same period of time might pass by much too fast. There is an explanation for that, and it comes down to this relationship: If you are only 1 year old, then 1 year seems eternally long, because that’s all the time that you’ve ever known. But as you get older, 1 year becomes a much smaller proportion of all of the time that you have experienced. For a 5-year-old, 1 year is 20% of all of the time he or she has been alive. At 50, the same period is just 2% of that person’s life. By the age of 80, a year will feel only about as long as a summer vacation feels for a first- grade student.
