Here's a wildly simple, profoundly interesting question: At what age are you happiest? According to a recent survey, the answer is 33. Friends Reunited, a U.K. website, found that 70 percent of respondents over the age of 40 said they did not find true happiness until they were 33 years old.
"[That age] is enough time to have shaken off childhood naivety and the wild scheming of teen-aged years without losing the energy and enthusiasm of youth," Donna Dawson, a psychologist, told Fox's Washington, D.C., affiliate. "Innocence has been lost, but our sense of reality is mixed with a strong sense of hope, a 'can do' spirit, and a healthy belief in our own talents and abilities."
