My 65th birthday lunch with the family, in The Swan at Wells.
At one level, nothing changes when the dial of the year encounters your 65th birthday. But it makes a difference: my father, at 65, was in good health and had almost twenty years of life ahead of him. He was delighted to wave goodbye to work he hated, and welcomed his new autonomy.
Life for the 'getting-on' is an instance of the 'bathtub model' of engineering failure.
Everything is fine-ish until the last few years, at which point hospital appointments crowd the diary. One hopes for calmness and serenity.
Still, with luck, that's a way yet. Plenty of time to comment on the idiocies of public policy, the hubris of engineers .. and hopefully the wonders of new science and great writing.
