Women, we care a great deal about being thin and good looking, whereas men mostly care about sex - ideally with women who are thinner and better looking than they are.

As relationships progress, the time you spend smooching diminishes. Where kissing was once an enjoyable entree unto itself, it becomes a mere appetizer couples hasten through on the way to the main course.

Subsisting on a diet drawn from one food group isn't healthy or gratifying. Even eating cupcakes 24/7 eventually would get old!

I don't care how handsome or fabulous or funny the groom is, or how sweet and accommodating the bride, or vice versa. Marriage is hard.

One study found that people who smile in childhood photographs are less likely to get a divorce.

Beyond the profound federal perks, married people make more money; we're healthier, physically and emotionally; we produce happier, more stable and more successful kids; we have more sex than our supposedly swinging single friends; we even live longer.

Divorce is contagious. That's right - when you have a close couple friend split up, it increases your chances of getting a divorce by 75 percent.
