Thank you OP and PPs for this wonderful nostalgia thread. Fun spotting who's pretty much exactly as old as me :)
Sitting up watching telly when ill - the Open University, public information horror films, the brown '2' ident on BBC2 appearing and disappearing. The stretchy BBC1 globe. (And when a bit older, being very amused and fascinated at the new posh globe with gold lettering underneath). On a similar theme, being completely terrified of the ATV ident ('In Colour') with the noisy fanfare.
Charles and Diana's wedding - a hazy memory of a street party and getting a blue plastic commemoration cup from playgroup, with gold lettering which wore off long before the cup itself went out of service.
Bagpuss, Bod, Bric-a-Brac, You and Me. Later on, schools TV - sitting on one of the two big steps of the TV room. Watch, How We Used To Live, various science programmes. And watching it when off ill. Stop Look Listen. Near and Far (scary vertiginous intro zooming out into space). The countdown.
Grange Hill, Dramarama, later on Press Gang (loved that). Being a preteen and faithfully watching Neighbours and Home and Away.
Hushed tales of 'the slipper' in primary school, though I think it had been phased out then. Being terrified of the headmaster in a way I doubt today's children are.
Being made to take a Haliborange tablet daily, although by then I doubt there was a real need - plenty of good fresh food available.
Orange juice as a starter.
Being aware of being very cutting-edge because my parents had fitted five-point orange seatbelts (with 'PRESS' on the red release button) in the back of the car. Seeing 'Don't drink and drive' PIFs and thinking it meant drinking any liquids.
Ice Magic coming out.
Brown cardboard library cards and stamps.
Having a BBC computer and loading games via external cassette player. Writing simple programs and getting 'Syntax error'. Using our old ITT television as a monitor. Banda-ed worksheets at school. Pages and pages of photocopied, but handwritten notes by the teacher for A-level. Being a very early email adopter at university.
Huge (national) information campaigns about the change from 01 to 071 and 081 for London dialling codes.
The Mary Rose and the Falklands being big things and discussed in (early) primary school. In junior school having to design and write a newspaper front page about the Challenger disaster.
Smoking still being allowed on long-distance express trains when I first went to Germany aged 18 or so. Unthinkable now.
