When I was a kid, I regularly had a sleepover at my grandmothers (she spoiled me rotten ) and my uncle still lived with her. He was a 2-3 pack a day man. Every morning we'd hear him get out of bed and have a coughing fit that sounded disgusting, and it lasted for a full 5 minutes.
Every time we waited in anticipation of him coughing himself to death.

And we'd jokingly take stuff off the walls (paintings, crucifxes, ...) and then waited until someone noticed the stark white outline against the dark brown wallpaper. It got re-papered bi-annually, but it always took on the same brown hue after a couple of weeks.

Me and my brother never even touched a cigarette, being so disgusted at the whole concept of smoking.
Sorry for going
