I laugh. Big laughs. Small laughs. Medium laughs. All kinds of laughs. Laughter is healthy, even if not appropriate in all circumstances. Places where laughter may not be appropriate: funerals, wedding ceremonies, when your friend is having a panic attack, when being mugged, when your boss is firing you, when you're sitting home alone in the dark. Wait, that last one—that's actually the best time for a good hearty chuckle.
