First, thank you very much for this thoughtful response. Yes, we've been in avoidance mode for the past several years. That aside, I find the problem being the 'funding' and, more abstractly, the 'liability' issues. Take me for example. I had cancer. I provided a very good background of my lifestyle to my medical team to try and assess what caused my cancer. They took the position of not committing to 'cause'. Heck, they wouldn't even theorize. However, throughout life science has taken the side (and sometimes the wrong side) in saying 'this' or 'that' can not cause cancer. I find that to be a sketchy paradox. Paraphrased: "we know this can't cause cancer", but "we can't tell you what caused your cancer". Now throw in 'funding' and 'liability' and I see a sketchy road in favor of the almighty dollar.
