Sad I have to rely on a Wikipedia link, but it explains it better than I. You do not like firearms, that is a different discussion, as far as why that sort of skill set is needed ? answer your question with a question- Why does someone train to throw a ball to another person at 99 mph.. or dunk a ball, or slap a puck into a net ( in the top right corner) etc. etc. It is a sport, there is no practical use for the skill. Your hobbies are things you like to do and are generally proficient in them, or you practice so you get better.

Don't be wearing your orange ball sweater out in public anymore after watching this video.
