Thanx for bringing both sides to our attention, Candace. This goes along w/my "people first" belief, although I still find it difficult to justify such research. However, should I ever be in the position where I would need medical treatment that came about due to just this type of research, I probably would sing a different tune. I try not to allow my emotions to take over but sometimes, such as when I see a glow in the dark cat, it ain't easy.
