Wanna know when you're finally going to say "screw it" and start eating donuts by the case?

A new survey found the ages when men and women are most likely to gain weight.  For men, it's 44 . . . for women, it's 38.

The main reason men gave for gaining weight in their mid 40s is that their career and family responsibilities are both peaking . . . so they stop having time for exercise.

The main reason women gave for gaining weight in their late 30s is their kids . . . whether it's being too busy with the kids to exercise, or eating out of stress.
