Many people gag or vomit in response to others vomiting. Is it the sight, sound or smell? Could there be a selective advantage? If a tribe member of yours ate/drank something that induced vomiting, then maybe it would behoove you to vomit too?

Why haven'y I heard of antimatter? I first got acquainted with it through Dan Brown's novel... So, when I started reading it, I was like "wow!"... But when I did a research about it, I realized it has been long known to exist. So why haven't I heard of it?
