I've called myself semi-retired for the past 17 years. At first it was a way to deflect questions regarding why I'm not working when I retired from my profession at 50 years old. Also, I worked 3-4 months a year at a CPA firm......the work had nothing to do with my engineering career, just something to do during the dog days of winter. Only this year, at 68 years old, do I finally use the term "retired"
