I doubt that religion can survive deep understanding. The shallows are its natural habitat. Cranks and fundamentalists are too often victimised as scapegoats for religion in general. It is only quite recently that Christianity reinvented itself in non-fundamentalist guise, and Islam has yet to do so.
This year I've really decided to get into the best shape of my life, and I've gotten there by changing not only what I eat but when I eat and how often, as well as my usual workout routine. The combination has made such a big difference, and I finally feel in the best shape of my life.
