Well, I was born in 1944 and it was a long time after I left school that it changed!
I was 10 when they deleted references to trams! (They returned
40 years later.)The Green Cross Code was introduced in 1970, when it replaced the Kerb Drill.
The Tufty Club for under five year olds had been introduced in
1961. I think we'd find the prospect of under 5's crossing the roads today rather alarming!
