Totally off topic, I invite all speculation.
I live in a northern environment. One of our neighbors keeps a window open with a large fan in it actively and constantly running non-stop all year round. The temperatures recently dipped as low as -10F/-24C for days. I have never seen the fan turned off once.
Just tonight another neighbor in the building (a police officer) was asking my wife if she thought they were dead. I’m fairly sure they are probably alive (based on noise), and I don’t think they are storing corpses… What in the world could be going on? At that temperature most illegal activity defies the laws of botany and chemistry.
PS: The fan is still running…
