I bought one after reading that story as well.
I’m glad you did.
So often people think it can never happen to them, and I think that’s even more true in warmer clmate places where we hear very little about CO poisoning because it happens far less frequently. I know that’s true in CA where I live.
But I’m another survivor of chronic carbon monoxide exposure - thanks to a detector.
Friends laughed when I said I’d be giving everyone a CO detector that year for Christmas, but I can guarantee the people close to me all have (at least) one in their homes now.
