Laughter

"Smile while you still have teeth." That's the answer I would give if you ask me how to live happily. Some say a smile is the best lubricant to shorten the psychological distance between people. However, I have never realized this function of smile. For me, it simply is a kind of habit - in other words, it's as natural as breathing. I can be amused quite easily. Therefore I've been struggling to seek out the reason for my natural inclination towards smiling and laughing. Eventually I decided to make the point that I truly have a way of observing something interesting in almost everything. Besides, I just feel amazingly good when I laugh. Nevertheless, there is one thing that really makes me angry with myself. It is completely presumptuous to find something funny over some serious matter and feel no inhibitions to laugh. Anyway, I appreciate all kinds of laughter: the laughter Scrooge had when he found that he still have the chance to compensate for his sin and save his own life; the laughter a blind man has when he sees the sun for the first time: the laughter a mother has when she looks into the face of her newborn child. Last, let's make laughter a contagious disease, infecting every man and woman.

[Excellent article.  I read the story of a man with a rare disease the stiffened him like a stone.  He could hardly move at all.  He put himself in a room for a month where he could watch every funny film he could remember and laugh at them.  He walked out of the room after the month was over, only a little stiff.]
