According to a British Networking site, In general we are at our happiest when they turned 33. Why this number exactly?

Because you are at an age where you are old enough to have hopefully broken away from your teenage ways, and still young enough to feel energetic.

Many people claimed that their happiness at 33 came from fulfillment in their professional lives, as well as having a support system of family and friends. Not surprisingly, 36% said they were happiest when they had children.

Also, many people at this age have a good job and are more financially secure. So If you are approaching 33 , things are only going to get better. And If you are over 33, you are good to go. Enjoy It! :)
