There's at least one 80 year old who is a regular at my local YMCA.

My paramedic friends tell me that the oldest folks they meet all live on the top of a five floor walk up.

Use it or lose it.

There's two different kinds of confirmation bias happening here

And at what point did I present it as anything else?

But since you're going to use the interwebs to act superior, I'll provide evidence, because doing a search takes very little time.

Oh sorry I was trying to poke fun at the idea that the old people on the top floor were being more frequently by paramedics (as opposed to the ones on the bottom who weren't). Survivorship bias might have been more correct to say.

I just found the morbid image of a health worker confirming that their patients are healthy as funny (since the actual healthy patients potentially never get visited)
