Do you think there is a correlation between health and religion?

Early in the national healthcare debate an interesting statistic came out. It was that countries with a national healthcare plane were also more likely to reject religion. When people feel they have a degree of security they are less likely to look to an invisible deity.

I have a few clues of my own. At one time I had 2 very good friends; one British and one Irish-American. They were both strong Catholics but over time became more tolerant and lax in their faith (they even moved in with their girlfriends). I lost track of them for 25+ years. One came up on facebook and one showed up via a mutual friend on e-mail. Both had grown fat, lost most of their hair and looked older than their years. And both had increased their religiosity in a big way. I have noticed a lot of evangelicals are in the same shape and I thought why have they become so focused on homosexuality and forgotten about greed and gluttony?
