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.

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.

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

Merely watching a romantic comedy causes relationship satisfaction to plummet. Apparently, the bitter realization that maybe it could happen to us, but it obviously hasn't and it probably never will, makes our lives seem unbearably grim in comparison.

What do women do when they get together? We sit around and talk! Men, not so much. My theory is that this difference is genetic and dates back to the hunter-gatherer societies, when the men had to be quiet as they hunted, lest they scare away the bison and then everyone starved to death and it was all their fault.

If you had asked me when I was 28 and in my wedding dress if I ever thought I would end up in my forties flipping my husband the bird over potato chips, I'd say you were crazy.

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!

Women tell stories men want answers. Guys get impatient when we drone on forever we get frustrated when they tune out.

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.
