After reading some of the heater thread it reminded me of when I was a
kid. About 40 years ago now.

Across the street where we lived was a group of small houses that were
occupied mostly by the elderly.

At least once or twice a year one of the houses would burn. Smoking
in bed was sometimes the cause.

It is a good thing now that everything is made out of flame resistant
material or I would be on that list. I have a couple of burn holes in
my sheets.

I know longer smoke so going to sleep with a cigarette is no longer a
problem.
