I was born in 1954. So the list is missing:
That Television has not always been in color.
That discs that contained music actually had holes in their centers. To be played on stereos.
Autombiles did not always have air bags. Seat belts or baby seats!
Jack.
Today's disks full of music don't have holes in the middle?
And those kids don't even know who Jack Deth is.
Do you remember that stereo records were a new thing in the late 50s, early 60's? I had one that had the music on one side and the voices on the other.
