Is it all right to stop caring at one point?

No, you must never stop caring, and you must never give up, and you must fight fight fight the dying of the light, Santa Claus will clone himself and Celine Dion just touched herself and went "Ah", and you're focusing on all the bad stuff (the news) watch John Stewart, not that Anderson guy, watch fiction on t.v. and the comedy channel and read Discover Magazine every month and laugh and play and get down and dirty sometimes and sink you arms elbow deep in the fun muckiness of life and get up off your fee', rock on...:)
