Did you know? When Michigan was a young territory, deer were so common and hunting such a part of life, that deer skins or whole deer were used as money. A deer carcass was worth a dollar, and hence, the dollar became known for what it was worth - a buck.
And the main reason sharks kill people is because they think your a fish. Also people kill more sharks, than sharks kill people. I can't remember exactly but its like every 1 person a shark kills, we kill like sharks.
