Back in the old days I remember no flat TV and a lot of problem with reception, spending a lot of time moving the antenna. The same with the radio and the channels wheel. Tape cassette, walkman and VHS.
No A/C in the home. No gas hot water heater but electric one that would last few time.
Cars without seat belts or airbag.
Shoulder pads that seem ridiculous today. Period pads for girls were very wide, long and tremendously thick, almost a diaper to wear with plastic protective underwear. In everyday life women didn't wear miniskirt, leotard, skinny pants or so tight t-shirt.
Mobile phones did exist but they were not common, when you were alone out of home you were really alone. I remember some home phone with the number wheel, half an hour to compose a call. Public phones with coins. Parents telling you infinite times to stop the calling with your friends.
Spanking were not an issue, widespread, even for teens, and there were much fewer bullies and brats (young and adult).
Then no PC and internet, so no social media, there were very big book to find phone numbers or shops. No GPS so if you got lost in the city you was lost. If a friend left you had very few contacts, only phone calling if you could catch him/her on the right time or just postal letters. And on vacation you sent postcard.
Many things were harder than today, many others more simple, poor or inefficient. Anyway I feel everything was more "true".
