My aunt had Alzheimer's at 90. she couldn't recognize anyone but the cat (by the name of one who had died 40 yrs ago, so we all called it Bingo to make things simpler), But she'd played piano at the church and if she found a keyboard, she could play at least 20 gospel songs from memory.
so nobody was around before '74? Cripes, if you can bare to ask any boomer, they'll tell you with a straight face it was absolute hell. but they knew someday a better world was coming.
FYI: Miercoles (Spanish for Wednesday) is to poop as "Got down & sat on a bench" is to "God D**n and Son of a Bi**h". It's the same expression for polite company or when your parents are within earshot. I suspect the same is true in the other languages too.
