Thats a great question and I also wonder why that is? perhaps we get upset at the sight we see and it makes our tummy nervous! Maybe scared or maybe just disgusted.....

It is a primitive system designed to prevent us from ingesting toxins or bacteria that could makes us ill. Put if this was, if something looks or smells awful, then chances are that it is, and will cause us harm.Hence why people feel ill looking at autopsies or poo.
Memory also plays a part in that if something has made us sick before, we remember it and it may well do the same again.
