I smoke cigars. Started about 3 years ago. Sometimes, its out of habit, will be standing in the cold, rain and wind... won't really enjoy it, and i feel like an idiot.
But then, there are times like this morning, where I go in my yard, and truely enjoy the moment. Comparable to eating your favorite desert.
Logically, I should slow down the amount I take so that it only becomes these moments I truely enjoy. But give up entirely? I don't see the point. Sure there is risk associated to it. There is also a lot of risk in driving to work, swiming in the lac, eating chips, walking a bit too late in the evening in some shaddy area, etc.
My point is: I'd advise control rather than full ban.
