why bother?

My son (9) just told me this afternoon (while I lay on the couch riding the waves of nausea because of a blinding migraine): "In five billion years the sun will expire and take all of us with us in a burning inferno." This started me on the discussion of mortality, yes with a migraine-- easy to do because when the pain gets really bad I'm at my most suicidal.
Like I have said earlier, I don't believe in Heaven but always had this notion of us "living on" in the DNA of our offspring and the words of our books. "Shit, William," I said, "Where does that leave us? And whatever we try to do in our lives? Why even reach for perfection if perfection disappears into the big incinerator as well?"
"I dunno," said Will,"but if I can 't study marine biology or astronomy, I think I'll try philosophy." Caroline (7) was in the room and I asked her, cross-eyed from my migraine: "Does not this bother you?" "Na," she said, "I live now and that's what counts." She continued to draw, her favorite thing.

Still...I have been thinking of chuckin' it all, sell my expensive Orinda real estate before the bubble bursts and find a little cottage by the sea in New Zealand. Here's to life and trying NOW...
Happy New Year to you all!
