history: I feel ashamed of all of the years of my life spent as a cigarette smoker I was a cigarette smoker for nearly an entire decade. In retrospect this is slightly embarrassing.  Don't be embarrassed. You know that you had a problem and you are better now for it
current: Right. Not much that can be done about it now. I enjoy having more money now though for sure!
next: That's understandable. I wish you the best in staying smoke free!
