Robert Putnam - Bowling Alone

"Moving from a state [or country?] with a wealth of social capital to a state with very little social capital (low trust, low voluntary group membership) increased one's chances of poor to middling health by roughly 40-70 percent. Indeed, the researchers concluded that if one wanted to improve one's health, moving to a high-social-capital state [or country] would do almost as much good as quitting smoking." ~Robert Putnam
