I just read a paper by Dr. B that used human skin samples to study parasite infections, which is really cool because 1) animal testing sucks and 2) the skin donors were women who had cosmetic surgery! How cool! I've never heard of such a thing! I've always thought that most cosmetic surgery is pretty silly, but what a great way to make it actually useful. Human skin samples are really hard to come by, like most organs. Why people don't donate their organs when they die is beyond me, I think it is the ultimate selfish act. But this, this was great. No one was killed, no mammals died, some useful science was done, and some women got prettier. What a world we live in.
