In my not so short life I have been an auto mechanic, including 10 years as a service manager and several years teaching. I have been in the computer business now for 26 years - 5 with a small manufacturer in product development and 21 years self employed as a contractor in the window business, the insurance business, and other small businesses including manufacturing .
Outside of my working life I have also built and drove my own electric car, and am currently finally in the back stretch of an airplane building project. - among MANY other projects and hobbies.
