Don’t be sad about getting older!  Research has found that happiness ultimately increases with age.  But there’s one catch- people tend to feel less happy as they approach 50, at which point they suddenly start to feel happier.  By the time they hit 85, they’re happier than ever before- even when they were 18!  Experts aren’t exactly sure why happiness increases in old age, but they have a few ideas- traits like self-esteem and overall satisfaction may simply accompany maturity, or perhaps aging makes people appreciate the value of life more.
