When I was at Uni we did an experiment where we had to skin a frog and remove one of the muscles from its leg. We then passed electric currents through the skin and the muscle and tested what happened.
That was over 10 years agao and I think it was the last time I ever did any experiments involving animals.
Well, I did chemistry at uni, and now work with computers, so I’ve never had to do anything particularly disgusting professionally.
I did, however, do some voluntary work in Mexico, doing sea turtle conservation. We had to collect data about turtle nests, and why some eggs don’t hatch any why others do. I had to dig up failed nests, which were usually full of maggots, and open up the fertilised eggs and look at the turtle foetus to determine its stage of development. That was pretty disgusting.
