Also kicked the smoking habit 20 years ago, but your post reminded me of something that happened in college one day when our young Psychology professor, usually a happy and friendly guy, came into class one morning very angry. He threw a pack of Marlboros on his desk and said, "That's it, I quit!". He went on to explain that his reason was not health related, but that the price of his cigarettes went up from 25 cents to 30 cents a pack! First and last time I ever saw him lose his temper. Don't know whether he actually quit or not but, several years after I graduated, he became Dean of the college.
