Well, as I fixate on my mortality I can take comfort that I’m still not as old as my dad was when I was born, and when I am – when he’s 90, as I expect to see – he’s on track to be in roughly the shape I remember his father was at 70 (and not just a generation and a half younger, I was never a tobacco smoker)

(I’d bet on 95 too, but it would be a bet)
