Another old geezer here. I have used outhouses and crank phones. It was always fun with party lines on the farm phones. All you had to do, was pick up the phone and listen in, participate in someone else's phone conversations. Other gone by the wayside tech:
steering column manual shifters
Push button auto transmissions
My first cell phone was a carry bag phone, weighed about 6 lbs.
4-track, reel to reel, 8 tracks in cars
Schwin sting rays
Prell shampoo - which I still use
