why ? I am becoming a happy man in my old age....where I was once a cynical bastard, i am now a smiling type of man who greets his neighbors every chance he gets. Why ? Is it the green tree outside my window ? Is it the tofu which I ate ? Perhaps it is only my individual bio-chemistry making me a happy man. My body wants to survive, and it knows that if I am happy I will last a longer time on this planet.
