So much, I'm proper old and even 1/10th of what was completely standard in a 60s/70s rural childhood would horrify the youngsters of today. It was in many ways a gentler, more naive time, the pace of change happening in cities was very slow to catch on and it was a bit frozen in an earlier time. Everyone knew everyone and everyone was to be trusted implicitly. The community as a whole looked out for the kids, and it was generally assumed everything should just carry on as it always had and everything always work out fine, people didn't worry nearly as much as they did today. But I'm not oblivious to how risky and dangerous that could be at times and I think we're bloody lucky that (as far as I know) no child was seriously hurt or killed in our village/area. Mostly it was a total lack of parental supervision on a daily basis - from the age of about 4 we were pushed out the back door to roam the villages, fields and local farms as a gang of kids, often staying out all day, casually wandering around farm machinery, slurry pits and so on. We'd go swimming in the local river or ponds completely oblivious to any risk of drowning. Our parents had no idea where we were and no phones to get in touch if there was a problem. If there was a toddler younger sibling you were usually made to bring them out too, since we quite naturally found them a drag they'd often be dumped somewhere along the way like a neighbour's lawn with some toys or put down somewhere to nap and we'd go off to play and pick them up later, or someone else would direct them home 
.
Small thing but I don't remember us ever drinking water, when today's kids are surgically attached to their water bottles and younger parents seem borderline obsessed with getting them to drink, we'd maybe have a cup of weak milky tea in the morning and another with meals, sometimes squash but this was a treat (and fizzy pop an even greater treat), but we'd run around all day long on a hot summer's day with no fluid intake at all? Perhaps I'm misremembering, I did sometimes put my head under the yard tap if I was really thirsty (the water was probably filthy 😱) and I do remember the other kids used to faint quite a lot so maybe that was the dehydration? We also definitely never wore sunscreen, I don't think we would even have known what it was, suntan oil was available to enhance how much you scorched off your skin cells but otherwise you just turned bright red and/or got sunstroke !
We had ponies (not as posh as it sounds, back then you could pick up a hairy bog pony for pennies and it could live for very little £ in a farmers spare field or barn) and our safety practices were poor to non existent and again very minimal adult supervision, we use to tare around the place with no saddles, no hats, sometimes no proper bridle or a bridle/headcollar held together with string. If someone's dad agreed to drive us and our ponies out to a further away competition or PC rally in his farm trailer or horse box we'd all ride in the back with the ponies (no seats never mind seatbelts) which is a bit 
, we'd have been toast if he crashed. At least the roads/lanes were significantly quieter then although driving standards generally quite low and the acceptability of drink driving very high! When we hacked over to pony club rallies we were taught what was what by the terrifying DC and licked into very smart shape but as soon as we were back home I'm afraid wild ways resumed fairly quickly. Not what the thread is about but I'm also retrospectively a bit ashamed of our standard of care of the ponies and some of the other animals, we loved them deeply but were clueless by today's standards and did things that were unacceptable today e.g. using the same badly fitting saddle on multiple ponies padded out with saddle cloths, never rugged or brought them inside in winter no matter the weather (we did trek up in 6 inch snow and dark to break the ice on their water troughs and put hay down every single day though), didn't worm them, vaccinate them or give them ulcer or joint supplements that are de rigeur today... other girls in the village had pet rabbits or guinea pigs and they lived in tiny wooden hutches and were rarely brought out which is 
.
Safeguarding was not a concept that had been invented and there were a number of very creepy characters around who were simply regarded as eccentric or with amused tolerance, it was well known for instance that one of the grooms/farm hands where we kept the ponies liked to creep up on little girls in the hay barn or other dark corners and touch their legs and bums, we simply just didn't go in the haybarn alone or if he was around - no thought of telling anyone or reporting him or anything 
. Another old man in the village would try and get the kids to go into his house with all promises of cake and sweets and so on and for some reason this was thought to be very funny and the subject of 'dares' to see how far you could push it with him before running away shrieking and so on - no idea if he was actually a predator or just sad/lonely/neurodiverse , no-one thought in those terms, again sad really that people were just written off as 'weird' and no further questions asked. In fact there was a massive, massive lack of tolerance of anyone even a bit 'different', homophobia and racism were rife, very little understanding of disability or mental health and these were generally felt to be very shameful things to be hidden away.
On the whole I think we have it better today than then even if sometimes I do get overwhelmed with enormous nostalgia!
