Thinking back to the olden days and remembering the excitement of being able to buy (electrical) plugs in white. Then along came rubber plugs - amazing!
Then changing sockets to white flush ones.
Putting a plug on my mother's iron so she didn't have to plug it into the light fitting.
Rocker switches - Wow - so modern.
A TV with a remote control (21 strand cable to it I believe).
My first house - I think I bought it because it had a Trimphone on a really long wire so that you could carry it into the lounge - wow - all phones used to be black and in a cold hallway.
I wonder how many jobs would have been saved if telephones had been freed from the Post Office monopoly earlier. (whilst we had a manufacturing capability)
Going to the Science Museum and seeing a door that opened as you walked up to it - Heavens! things would never get this fantastic
