What sort of people engage in recreational group sex on a regular basis? David Schisgall's documentary The Lifestyle provides one answer: mostly cheerful, but paunchy, suburban couples who have either slipped into middle age or are starting to advance past it. For the most part, they look like normal workaday folks, and could even be your neighbors. Schisgall interviews 20 members of "swinging" groups in Orange County, CA, and discovers most are happily married (often for decades), politically lean a bit right of center (several of his subjects once had careers in the military), and are personally unremarkable once you get past their "hobby." The Lifestyle also reveals why AIDS is all but unknown in "swing" circles and takes a trip to a "Lifestyles" convention where fun seekers from around the country get to know each other (in more ways than one).
