ok, don't even read this if you mind is closed
right do fish feel pain, well yes in a way, but they don't feel higher pain, this was demonstrated on the tele, by someone putting their hand in a box, so they couldn't see their hand, and a fake hand with a rubber glove that they could see on a desk, both the fake and real hand that they couldn't see were stimulated at the same time, until the person felt that the fake hand was the real hand, when i pin was pushed into the fake the fake hand the person felt the pain, this same trickery could be used to develop sims game controllers.
i've added this as a reminder to me and that someone might take it further.
