According to a recent Gallup poll, American Jews are the happiest people out of any religious group:

The Gallup-Healthways Well-Being Index is based on a survey of more than 550,000 people who were scored on a number of categories, including emotional and physical health, work environment and healthy behaviors. Jews were placed in the No. 1 spot, with an overall “well-being” score of 69.8, followed by nonreligious or atheists/agnostics, Catholics, Mormons, Muslims and other religions. Protestants scored the lowest, at 64.8.

I guess this means all the therapy is finally paying off.
