I've been making a list of things that didn't exist when I was born.
I began to notice a lot of things, not big things, but things that were introduced sometime in the last forty-odd years. I'm working on a webpage to list them and comment on the changes these things have made, and what it was like not to have them, but I also need to do some research and make sure that these things really didn't exist in 1967 and not just that where I was, I hadn't heard of it.
So -- help me out. If you see something on this list that doesn't belong here, or if you can think of other things that do, let me know by emailing me at email@example.com.
