A study has suggested that people are most content at the age of 33 even though school days are bound to trigger nostalgia.
According to a survey conducted by a website Friends Reunited, seven out of 10 people over the age of 40 picked the year they turned 33 as their happiest period of life, the Daily Mail reported.
Over half of those surveyed -- 53 percent -- said life was more fun and 42 percent said they felt more optimistic about the future.
One in three said their happiness stemmed from having children while one in five said happiness came from success at work.
Life seemed relatively stress-free for 38 percent while 31 percent thought that was the time their family was closest together.
Only six per cent said they felt happiest being at university and just 16 percent in childhood.
Psychologist Donna Dawson said: "The age of 33 is enough time to have shaken off childhood naivety and the wild scheming of teenaged years without losing the energy and enthusiasm of youth.
"By this age 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".
