>>>When you and I were kids, there were no bicycle helmets; so nobody wore one. When my dad was a kid, there were no seat belts in cars, so nobody wore one. Good ideas evolve.

>>And everybody smoked. On (in) the buses, trains, movies, parliament sessions, ambulance waiting rooms. We are practically kids of people who must have died before they met, they all smoked so much.

>I was a 2 pack a dayer once upon a time (25s, not 20s), and I didn't smoke at work. I was pretty much doing most of those 2 packs in the evening. So, I refuse to comment on other people's smoking, no matter how stupid a habit it is (this is me not commenting).

I stayed firmly at pack a day. Actually, I rolled my own, and after a few months of writing the dates on the lid of the can when I'd open it, calculated it at 18g/day. Now about a quarter of that remained in the butt, often more than that - it would just extinguish in the ashtray (a pompously sounding Latin verb, isn't it). Nevertheless, I kept at it for 32 years, and didn't really have the symptoms. Not any that I didn't have before ;).

But it started to raise my blood pressure. At every humiliation one has to endure for smoking, even at home.
