The number 17

Yesterday, Ash Wednesday 17th February 2010 was the 31st anniversary of my marriage to Sukie, my first wife. 17 is a prime number, as is 2 and 1979. And 1 + 9 = 10, 1 + 0= 1, 1 + 7 = 8, 8 + 9 = 17, which is odd in a nice sort of way. 17 has always seemed to be a good number or a date on which things happen to me, and I just like it. In the same way perhaps as the late great Douglas Adams had a thing for 42 (or did he?).
