No, I don't mean that they were all accidents and that you dropped them on their heads as babies. What are some things that you grew up with that have gone the way of the dinosaurs (or will go extinct soon)?
For example these are some of mine:
VHS tapes
Floppy Disks
Film cameras
Answering machines
Payphones and phonebooks
Phones that are only used for talking to people
Blowing the dust out of nintendo cartridges
Manually unlocking car doors
Public libraries
Using a road atlas and not google maps (or another service)
Add your own and if you're really old (over 30) be sure to include things like:
Using a horse as your main form of transportation
Using Morse code
Living in a time when only white men could vote
Films without sound
Polio
Sitting for portraits
American flags with fewer than 45 stars
