That's true, Rap, thanks for responding. But, the only "cause" folks have to take up is taking charge of what they eat. If one truly wants a change, one which could prevent such terrible dis-eases, it seems one would do just about anything, including changing to a whole foods, plant-based diet. And, as it shows in the docu, that's not just about a bunch of long-haired hippie freaks, or "sissies," spouting veganism; it is mainstream docs, researcher scientists and case studies of even seeming "macho" men who have changed their lives by doing so. I'll get off my soapbox now, but I do wish anyone who really wants to do their best to stay very healthy would watch it and take heed.
