Old, Male and Republican - the Keys to Happiness

So says a report on LiveScience.com:

Happiness Is ... Being Old, Male and Republican

Americans grow happier as they age, surveys find. And a new Pew Research Center survey shows the tendency is holding up as the economy tanks.

Happiness is a complex thing. Past studies have found that happiness is partly inherited, that Republicans are happier than Democrats, and that old men tend to be happier than old women.

Three for three.
