I don't hate them. I really really really dislike people to say, Its OK and it will get better. I could have gangrene in my big toe😫
I suspect there might be an ethical or legal problem with that, but I really don't know.
My reaction is mild revulsion, but I don't have intellectual position on it.
I sure couldn't find anything like that ever being done. However, they have used a pigs heart to transplant in a baboon with success. Best I could do.
