First time and last time I felt old.
First time I felt really old: me and the g/f would occasionally "babysit" for a family down the road, mostly just looking after the kids in the day when mum popped out to the shops and they played in the street. Three boys all under ten, little gems they were. One in particular was a real star, bright, funny, you could have a proper conversation with him (he had some controversial views on Schumacher's pit stop strategy at the 1998 Hungarian Grand Prix, for instance) which sometimes made you forget how young he was. My bestest mate and I were talking to him about something or other, and described something as gliding across the floor "like a Dalek". And the lad said "What's a Dalek?". And it was at that point that me and bestest mate looked at each other and realised that the last time a Dalek had been on telly was before the little fella was even born. He literally had no idea what they were. (And probably remained in blissful ignorance for another seven years before there were Daleks everywhere again)

Last time was the other week as I was walking up a hill as an immediate prelude to flying off it on a paraglider. Paragliding is mostly a fairly old man's game, but the bloke I was walking up with seemed quite young. I asked him what year he was born, and realised with some depression that I'd graduated university before he took his first breath.
