That's freaky... not to mention DISGUSTING.
I really hate those situations...
One of my lab teachers for my subject used to experiment on rats, over and over, to what? to find out information he's found out 100 times before?
He used to be cool after I knew (he is still a "good" person in a way I guess) but now i think I hate his guts.... Honestly anyone who can do that sort of thing and not mind and even talk about it like its cool isn't worth my time.
It's good your lecturer was understanding ( a bit) , when I told him it was disgusting, well he got all defensive and said he saved one white one that was his favorite... >.>
all I can think of is WOW, aren't you the hero? *sarc*
Anyway It's really hard to get away from that sort of stuff. We have to do stupid animal dissections in class all the time, I get in trouble for not participating though (which is absolutely pathetic) I mean, yeah I believe the thing has 4 heart valves (I hope I got that right otherwise I'm stupid

) , I don't need to prove it myself.
I just know I'd NEVER do research, unless it involves humans
