I retired after 33 years teaching college-level courses in philosophy (including logic), and began taking Microsoft Authorized courses to earn several certifications.  I also earned the A+ certification.  I have taught in tech schools and on contract for a corporation.  In the past few years, I have operated a solo tech service focused mainly on users of my own generation.  I do installation of new systems, troubleshoot  hardware and software, give personalized tutoring, and offer instruction in Win OS and Word through our Learning in Retirement Program.  I continue to delight in challenges and learning new skills.  The contrast between the petty competitiveness among academics and the helpfulness in the computer community could scarcely be greater.
