David, the survey sounds like a great idea....not only would we participate, but would look forward to the results of your findings. Since my husband had recurrences, we have definitely cut back on red meat, I make him (yes, pouting and cajoling my specialty) eat more greens. I run broccoli thru the blender to add to the broth for my chicken noodle soup. I do a lot more cooking in olive oil, and we both drink lots of green tea, etc, etc. We both need to get more exercise however. And we are also with Karen in that a positive attitude contributes to a healthier system. My husband never smoked, or chewed, and rarely drinks, so we didn't have to eliminate those possibilities. But like others here said, because he wasn't in the "80%", it was just plain bad luck. What do they say? If I didn't have bad luck, I wouldn't have any luck at all?
P.S. David, we are in Sarasota, Fl. and have cats too JaneP
