I guess depression comes to certain people for a variety of reasons. I agree with the starting post that lots of people, especially as they get older, are lonely and bored. I'm sure it causes them to feel depressed and I'm not sure if any med would help that. I eat crappy, really don't exercise, avoid the sun, live alone and have never experienced a depressed day. I personally prefer online interaction. That way, when I'm done with people (LOL), I can just close my laptop and get back to the somewhat hermit life I love. I am an artist and can spend days without people. But I think, for lots of other folks, the loneliness and lack of face to face interaction is a very big depression factor.
