I turned 52 yesterday. The first decade of my life took 20 years. The second decade took 15 years. The third decade took a decade. The fourth decade took five years. The past dozen years took 12 minutes. At this rate, I'll be dead in less than half an hour.
Addendum: My mother and stepfather visited me from Michigan yesterday and today. I hadn't seen my mother since 31 December 1993, when she was 59. She's 74 now.
