One of the reasons I quit smoking cigarettes finally was the fact that I fell asleep with a lit cigarette in my hand for the 1st, one and only time of my life to burn my pajama shorts, my grips an my skin. No flames but big burn holes and I almost lit the bed on fire. I quit cigs the next day and that was more than 5 years ago now.
Did you ever burn a 1" wide part in your hair down to the scalp because the carburator backfired in your face? I did.
