That is so crazy , I didnt know that.....hopefully eventually we'll be able to grow our own hearts and junk like it was nothing.
Also, the whole pain for the animal points are good but i would like to add another thing, lets just say everything they tested wouldnt kill or mame them in any way, they still would be in a little box their whole life which is why i try to buy things such as my chapstick that werent tested on animals, but medicines for cancers and other horrible diseases if it was put to a vote, I would vote for them to be able to do it. These meds are also tested on ppl after their tested on animals they are tested on ppl willing to do it or who want to do it because it may help their disease, so we do it too. And, I'm also a complete donor, they can and probably will have my eyes after I die so they can go to someone who will be able to live a better life because of them.
