Born 1956, so older than most of this thread. Randomly...
My mum learned to drive in Somerset when I was about 2, on a banger in a farmyard.
We lived in a caravan in the farmyard although my dad was a junior officer (too young for a quarter in those days). My parents bought their first cottage (no heating apart from the fireplace) for £1900 in 1959 when my sister was born.
We were middle class, from working class backgrounds.
My mum learned to cook, and eventually became good at it so we ate sensibly but portion sizes were tiny compared to these days, and to this day if you eat at her table, portions are more 1970s than 2016.
When I went to school, in west Cornwall, transport was not provided unless you lived more than 2.5 miles from school; otherwise you walked.
Some of my family smoked, but my great grandfather still lived to 89, and was one of 12 children, who all made it well past 80.
There was sherry at Christmas and a bottle of Hirondelle for a dinner party of eight was the last word in sophistication.
OTOH, my mum didn't have a washing machine for years; sheets and towels were sent to the laundry weekly but nappies were fabric and washed/dried at home.
The butcher's van came twice a week and veg usually arrived via a farmer's boot and was whatever was in season. Fish was sold door to door off a string if someone had caught a load of mackerel. Flour, rice and staples were bought loose by the pound from the village shop. The arrival of the supermarket (Presto) in the 1970s was a revelation, and it was 15 miles away.
We left the house early in the morning to roam and play and were summoned to meals by DMum's air raid warden's bell; we wandered around across about eight square miles, doing whatever we wanted, without adult supervision. There was only a hour of children's TV each day. It was quite austere, but blissfully free range.
No processed foods, and much smaller portions, and a lot more activity.
