Yes I and my friends did play outside ( unsupervised) . What did we have to be afraid of back then?
when someone was a pervert they were no where near where we lived in a very safe , very small town. When we were very young we stayed in our own neighbor hood! We were allowed to go further as we grew older. We were always safe.
Our lakes and ponds , ( could have been dirty) don't really know, but no one ever got sick after swimming! Most of the time, ( when it was hot, we got cooled off with a galvanized tub full of water.
that was So much fun, the summing pools of today can not compare!
We had several tree houses, Who told you the wood was dirty and full of germs. Loved those tree houses , we also had abandoned sheds etc.. where we had club houses. Fun, Fun We were wild and free and the only limit to fun was our imaginations!
We had water back then to get clean, It may have been a sponge bath, ( not in a tub) but it took the dirt and germs off of us. then we went to bed in a nice clean bed with sheets that were dried outside, smelled so good!
The food we ate back then was not junk food it was natural foods. Manufactured foods and synthetic foods are not necessarily good for you!
You sounded like my kids, You say olden days ( before Woodstock) They use Too ask me about the olden days and referred to them as prehistoric days!LOL
