"Studies say that people who have friends live longer and have fewer illnesses, and that close circle of friends actually helps the immune system work. With this in mind, run, don't walk, to your nearest coffee house, church group, library or political club. You won't find that 'close circle of friends' by sitting at home reading National Enquirer and watching TV! You do want your immune system to work, don't you?"
