Today 40 years at the same job is a bit of an anomaly. In terms of looking back on those 40 years, don't forget to value the fact that you were paying bills, paying taxes, supporting family and doing what needed to be done. So, I agree with BluesDawg that you must like some of what you do, or.... you're a much more disciplined person than most. The longest stretch for me is my current position at 23 years. Prior to that I had a seven year stretch, preceded by one five year, two four year and three one year stretches. When I was young (16) I had no idea what I wanted to do or be, but had to work. So, I changed jobs pretty regularly. Today, I can't imagine what I would be like if I had stayed at any of the jobs, save my current one, for even ten years. I'm guessing that during the 40 year span there were periods where you had to overcome and/or tough it out. These are traits that many cyclist know first hand. OK, enough with the ramble.... Congrats on reaching this benchmark.
