My 70th birthday is planned to be on 4/15/16, and if I survive that long I'll have _two_ birthday parties.
They'll be surprise parties because I'll be surprised to live that long. I expected to be killed about ten years ago by an overdose of brownies or by someone I pissed off.
Survival is the best revenge and I'm not embarrassed to show my gray hair. In fact, I'll add some gray hairs for the celebrations.
