For those who have an interest in the goals (even if not the means) discussed widely in this thread, there's another documentary movie that's creating a good deal of buzz:
About the Issues » Escape Fire
While the film is talking more broadly about problems with the health care system globally, a good deal of it does get into prevention - where lo and behold we see some of these pesky arguments that eating better and exercising more could make an enormous difference in our health and health care. If you're on that track of thinking already, the film might be your cop of tea. And if not, then I'm sure you'll find the same grist as usual.
As you might expect, it's packaged well and at least superficially compelling.
