Everyone has pretty much already covered it. The relaxation, forcing me to sit and take time out to have a smoke; the camaraderie of it with buddies on the golf course or you Bums here (which starts with cigars and extends into life in general); the wide variety of new sticks to try and as Kevin said above - just the physical act of slowly smoking a good cigar.

And since no one has said it yet, but someone will........ it also provides a little quiet time away from the better half LOL
