I couldn't possibly smoke more nor, enjoy it more than when I worked at my career. I've been retired from my career since 1986. Now I can work at what I like and make as little or as much money as I wish.
When I had a career, smoking was still socially permissible in the office and my G-ride. So, nothing changed in that respect. I'm actually smoking less as it is no longer permitted on planes, in rental cars, restaurants, hotels, etc. So, I'm saving a bit of money also. My self-employment operation permits me to spend most of my time out of doors, when not traveling, where smoking is, for the most part, permitted.
I enjoy smoking as much now as I did then or I'd quit my wee vice and save a few thousand a year. It is an expensive exercise.
