Sudoku addict. Retired three times, once as a fire chief, once as a construction estimator and once as a junior college teacher (solid state physics and electronics). I like solving puzzles and going to better restaurants. Having worked 46 years full time, I've been involved in several interests including civil engineering, restaurant management, construction, and my favorite, cardiology (EMT) No, I'm not a doctor. I don't even play one on TV. Primary hobbies are languages and rockets.
