AOL and Yahoo email adresses - I don't know I just assumed that they would cease to be active after a certain point, since AOL of course doesn't exist now and yahoo is largely abandoned. A friend of mine gave me his email a couple of months ago and I cannot describe my shock that he was still running his yahoo adress.
I think this is just a silly gen-z thing, doubt anyone feels the same, but I figured it's pretty funny
In the US (midwest specifically) I actually havent seen one of these at least a decade. I was just thinking they might be pretty beneficial to bring back around (dead phones, cant afford a phone, emergencies where one of the prior two applies especially)
