Ooh Ok... I was born in the early 80s so I can remember what it was like from a child’s POV:
Sweets were often full of s* that would not be allowed these days
Nursery and school were a lot more rigid and formulaic in the way stuff was taught. Teachers used to shout a lot. At primary we had a class computer on a trolly and had to take turns with it rather than an IT room.
There was a LOT of smacking. My parents rarely did buy some of my friends got smacked all the time.
Music came on tapes mainly in our house in the 80s. I don’t remember us getting a CD player til the early 90s.
Cars were very square and used 4 Star (leaded) petrol that was found to cause brain damage.
I was a bed wetter and there were no DryNites or Pull-ups like my DD’s had so I wore the largest size of plastic disposable baby nappies (which were huge!) at night until I was far older than I care to admit.
Everything was full sugar, including Ribena (which I’m sure was the cause of the problem, above).
Smoking. Everyone seemed to smoke. The world smelled of smoke. You could smoke anywhere.
Saturday Superstore on Saturday morning TV (which later became Going Live).
The music which was on in the background was so memorable that hearing some songs on the radio now triggers memories.
No mobile phones. I remember my Mum using payphones A LOT when we were out and about.
Coins were bigger and chunkier.
Mister Men lolly iced were the best thing ever.
