We used to build TeePees out of blankets thrown over the clothesline and actually sleep outside

!!! or on sleeping bags in the front yard. Nowdays, you just can't do that, you never know who'll be wandering around out there.
Anyone ever actually had a Dr. make a housecall to you? I did back when I had chicken pox in '72 or so.
And what about:
Cars that weren't even made with seatbelts
Waiting in line at the gas station for 1/2 hr
Out of gas signs at the stations
When regular gas meant leaded gas and it was called Ethyl
Local kids programming like J.P. Patches and Wunda the Witch in Seattle and the Santa and Kakeman show in Wichita (anyone who grew up in Wichita in the 70's will remember Santa and Kakeman and all the reindeer going zoooooming around the big wide world and zooooming and zoooming and zoooooming, god I miss Kakeman!)
Black and white TV
Bill collectors who actually showed up at your door (parents got a couple of them)
Smoking anywhere and everywhere. I remember my daddy smoking in the grocery store, at his desk at work and even in the church basement
(Hmmmm maybe my childhood wasn't so great)
