Reminds me of the scene from Monty Python and The Holy Grail:
BLACK KNIGHT: 'Tis but a scratch.
ARTHUR: A scratch? Your arm's off!
BLACK KNIGHT: No, it isn't.
ARTHUR: Well, what's that then?
BLACK KNIGHT: I've had worse.
Head wounds bleed like crazy but you are absolutely correct that a hospital visit is not ALWAYS necessary. Many times pressure, cleaning, and a little bit of logic will deal with it quite effectively.
