Birthday Cake

What are the happiest "Happy Birthdays"?

FOX News Radio's Sal Giangrasso reports:

A British study shows people are most satisfied at the ages of 23 and 69. The Center for Economic Performance at the London School of Economics says 23-year-olds are filled with optimism. While 69-year-olds are most likely to count their blessings.

The study adds people in their mid-50's are most likely to feel down, with regrets over unrealized dreams.

We asked some New Yorkers their favorite ages...

(New Yorkers) "25, that's the year I had my son.//18, that's the year I got married.//At 16 you're carefree."
