Something that's in the back of my mind...and I sort of don't think it's even important, but just maybe..so I'm throwing it out here: In some of Annie's research, her mice were developing cancerous cells. She was also working on pregnant mice. It's probably nothing, but is this something that may have bothered him? I haven't seen where she'd done work involving larger animals, but I've seen a canine mentioned a couple of times...not sure if her research is connected, though. I honestly don't think this is an animal rights thing, just wondering and thought I should put it out here.
