Former IT pro, age 79. I built my current PC about 15 years ago and upgraded it maybe four years ago. Once upon a time, I knew a fair amount about PCs and Windows networking, but haven't worked with that stuff for several years because I finally got to retire. Nowadays, my computer focus is on editing videos for my barbershop chorus and designing/slicing models for my 3D printers. Of course, I also keep in touch with my children and grandchildren on Facebook, Instagram, etc.
