SHARKING is a myth............

[alstl]

I've found the best way to deal with sharking is with humor. If you let it bother you that is the only way it can get to you. If you laugh at the guy then he gets unnerved because he isn't used to that reaction.

Physical contact is different but noise can be a lot of fun.

IHMO, it's the sudden change in noise or visual.

If the room was at a steady constant noise level, you get used to it. But if the room is a constant medium sound level and then suddenly as you shoot someone shouts loudly directly behind you, that will startle anyone.

Same goes for visuals. If there is no movement in your visual line and then suddenly as you shoot someone walks into your visual line, it's going to affect you.
