For much of my pipe smoking career, I smoked an average of 4 to 6 bowls a day. In the last several years my consumption has definitely reduced. These days it's rare that I smoke more than 2 bowls a day and often 1 bowl a day. Many days I don't smoke at all. Have any of you noticed an increase in your bowl per day count? Is it a personal trend or does it vary a lot over time?
