I worked up until last year, when at age 62 I decided to retire -- mostly because I could! A good portion of my career was in traditional, more hierarchical industries such as rail and steel, where a sizable number of older employees were often the norm. I also tended to specialize in legacy applications that other (mostly younger) staff didn't really want to touch -- products like PowerBuilder or IBM (Lotus) Notes. Yeah, I also did work with newer technology, but I never really let go of the older stuff because 1) it was the core of my earlier experience and I didn't mind working with it, and 2) there always seemed to be a need for someone to do maintenance, updates, or conversions.
