Yeah, as Woolie said, they've definitely discussed this before. And as I've also mentioned elsewhere, my response is the same: DigiPen. It was certainly not great, at least in an olfactory sense.
Also, related, I've been in houses that have utterly reeked of cat piss/shit. When I first enter a house like that, it's like a wall of stench that almost physically prevents me from even making it past the door. And yet, after I've been in there for maybe ten to twenty minutes or so, I don't even notice the smell that much anymore, which is normal, but also worrying and alarming. It makes me never want to enter those houses again in the future if I can at all avoid it, that's for sure.
Body odor is the same way. Especially your own. If you ever find yourself sniffing and noticing that you're a little ripe and in need of a bath, rest assured that everyone else has probably already been smelling you for quite a while before that.
