Things certainly have altered. Compare yourself to Harold Wilson when he was elected in 1964. He was a year younger than you are. When I left school I thought the headmaster was a Mr Chips type who had stopped on out of love for the job. He seemed like a relic from another age. When he died and there was an obituary in the local paper I discovered he was 45. I was older than that by then. My wife still asks what I want to be if, rather than when, I grow up.
