Sounds like you got a bad deal, man. My biology professors would NEVER have said anything like that, and I've never heard anyone in the faculty, or in the scientific community I've been privy to, state these things, because there is no evidence.
Holy crap. Wow. Thanks for all the years of fun, Dave. I still remember playing Killing Floor while listening to the radio show when the Amazon breakage happened. I wish you good luck going forward with whatever you're doing next!
