I have to tell a true story about this. A bunch of years ago I got to work and had a voicemail from an employee. She said, “I’m not coming in this morning. My carbon monoxide alarm kept going off all night, and I hardly got any sleep. I’m just so tired.” The way she talked, she sounded really out of it. I was worried that she had a carbon monoxide leak which was making her not think straight, and that it could be fatal.

This was back before it was common for managers to have an employee’s personal number. I called HR to see if I could get it, but they didn’t want to give it to me. I spent quite a while trying to convince them to give it to me, or to call her themselves. I was making some progress when she called back. Said the landlord couldn’t get it to stop going off either. I asked if it could be because it was a real leak and she said she didn’t think so. I told her to at least open a window. Never really heard more about it. It was honestly pretty frightening.

Plot twist: the detector is broken but the carbon monoxide gave you a tinnitus

A good method to commit suicide
