I would count laughter as a sort of Medicine. That's one of the good benefits of having life long friends, they can comfort you when your down, help you get over pain, and if their good at making you laugh then I say that is a good medicine. I wish I could laugh more, I just always seem to be down all the time, but for me its kinda hard to put on a smile let alone laugh. But yes I do agree laughter is a good medicine, not the better medicine since you might still need to take meds, medicine, rest etc. But yeah laughing is one of the best parts of being alive, savor it to the last drop.
