According to a new survey, the happiest age in a man's life is . . . 37.  That's right:  It's NOT in his 20s when he's single and well, ya know.... 

The survey found men feel happiest when they have some good career success and are starting a family . . . but not old enough that they're having health issues or approaching a midlife crisis.

The survey also found the top moments in a man's life that make them the happiest.  Men could vote for up to three things on this list.  Here are the results:

#1.)  Becoming a parent, 43%.

#2.)  Getting married, 35%.

#3.)  Seeing his favorite sports team win a championship, 18%.

#4.)  Buying a new house, 17%.

#5.)  Proposing, 13%.

#6.)  Graduating college, 9%.

#7.)  Buying a new car, 7%.
