Yes. I smoke. I also drink and gamble. I cruise a couple of times a year. When I was young, every one I knew started smoking around the age of 10. I have been smoking a pack a day for over 70 years.
Interesting thing. I brought up the subject with my doctor about quitting and he kind of smiled and said "at your age and the time you have smoked, the stress of quitting would probably give you a heart attack before you came down with cancer". Hummm.
At 81, I don't plan on changing my ways. Also, it seems that the smoking areas have the most congenial laid back cruisers on the ship.
