I look back at many people with Vices and wonder . . . Even though I find it distasteful, perhaps, this is what brings them happiness. Isn't the pursuit of Happiness what we should strive for in life . . . Isn't this the difference between living and existing?
I look at Christopher Hitchens . . . He loved to drink and smoke and you can find numerous videos where, like a "Lounge Singer", He has a scotch in one hand and a lit cigarette in the other . . . When he was diagnosed with cancer, I don't think he had that many regrets with regards to these vices. Here was a man who clearly knew that this w=life was all there is and chose to live it in with vices that shortened it but made him happy.
My Father-in-law is bound to a wheel chair. What truly made him happy in life was to be out in nature and to hunt. Now he is "existing" in a wheel chair. He gets up, the nurses put him in his chair, he watches TV and reads . . . Eats 3 square meals and repeats each day. The pharmaceuticals he takes keeps him alive, but he is not living.
