You know that friendships counteract the harmful effects of stress hormones, but new research says the more friends you have, the healthier you'll be.

Students who reported feeling lonely produced fewer antibodies, as well. Start a book group or check the Web (try Meetup.com) to cultivate hobbies and meet new people. Link
