What Would Be A Great Invention In Your Opinion?

I think some sort of camera that was installed into your eye so when you saw something you wanted to take a photo of you just blinked and took it, so you would never again miss one of those once in a lifetime moments.

Isn't that called memory? :0)

I would like a viable bicycle that would fold up small enough to fit in your pocket.

Alternatively, a jacket with really, really big pockets :-)

Wow, look at that!...
I hope a lot of elderly people wear them. I wish my poor 92 year old FIL had them on when he fell and smashed his hip a few years ago.
Thanks for that, Bednobs.
