Dirty Harry 44A school mum sitting next to me as we watch our sons play tennis offers congratulations, and says “welcome to the 44 club”. Her youngest is now nearly in school, and I had always thought she was my age or younger: frankly, I didn’t really think about her age at all.

There it is. Who gives a mental number to someone they meet anyway? And as it goes, age is nothing but a number.

Perhaps having kids later keeps you youthful! Now that’s not a wishful thought, that’s a liferaft.
