FYI: The author's FIRST JOB was in 1963, at age 12, delivering newspapers for the Los Angeles Herald Examiner. There must have been at least five children from my neighborhood who were newspaper carriers. Today, you rarely see anyone delivering newspapers. The Herald Examiner went out of business in 1989.
His next job, as a teenager, was working at a machine shop that made tools for aerospace companies, such as McDonnell Douglas and Rockwell North American. The machine shop is long gone and so are many of the companies it served.
