I used to be able to gut a deer, accidentally slice open his stomach and go "that's stinks."
No more. The older I get, the more sensitive I've become to smell. The visual part really doesn't bother me but "Oh that smell.........", it makes me hurl. My kids blew chunks a while back. The sight didn't bother me until I tried to clean him up. I joined him.
My wife (the nurse) called me a social puker. I can't handle it!
As for blood. Mine doesn't bother me at all. But other people, animals I can't handle it. I'd love to hunt too. But I'd have issue with the gutting. The older I get the less I can handle it too.
Oh, and I am poop impaired too (wifes term) I can't clean that up either, although when she was really sick I handled it. So it's a mind over matter thing.
