Laughter---How healthy is it?

Did you know that laughter can be used as a coping mechanism for stress and though it seems to be used as an outlet for the emotion produced by humor or happiness perhaps it actually produces the humor and happiness that we feel more than the other way around!  Ergo--do we laugh because we are happy OR are we happy because we laugh? It has been found that both of these statements are true, but we usually only exercise the former and why is that?  Laughter is a fascinating phenomenon that works just like a medicine BUT ONLY BETTER…although most drugs affect everyone differently, laughter is always the same---IT IS A ONE-SIZE FITS ALL! Laughter exercises the entire body causing us to feel relaxed and pain free AND IT IS FREE! The fact that laughter is good for one's health should be quite evident and yet adults laugh very little. Why is that?  So why not laugh and laugh often? When one laughs it is like taking a drug and yet there is no such thing as an overdose or laughter-toxicity!  Maybe we can now say…a laugh a day keeps the doctor away?(Adapted and made my own from http://home.hiwaay.net/~garson/laughter.htm)
