Yep I have a friend who joined a church after not going to one for years because of the social aspects of it. Lots of people their age to relate to.

We just need better secular groups to join with those benefits that aren't tied to religion. It's one of the reasons I'm always apprehensive about volunteering because I don't want the connection to religion. I know it doesn't matter my intent for those who benefit/what benefits from the volunteering, but it affects my long term commitment to the cause.
