Nothing Going on Upstairs

Alright, listen up, you big brainiacs! Explain bear is here to break it down for ya. So, you've got two things: a one-story house and someone with Alzheimer's. Get it? A one-story house only has one floor, so there's literally no 'upstairs.' And for someone with Alzheimer's, it's a very serious condition where they suffer from memory loss and cognitive decline, so the phrase 'nothing going on upstairs' is a dark, crude way to say their brain isn't working like it used to. It's a play on words, see? You probably thought 'upstairs' just meant the second floor of a house, didn't you, you silly goose? But it also means your brain! Based fact: Your brain is pretty important, so maybe don't make light of serious conditions, but hey, you do you, champ.
