Yes, my beard is grey!
I am retired and come from a varied environment ranging from construction to office work (CADD to IT). Though I know enough about computers to get myself into trouble, I also know enough to help some get out of trouble.
I am “handicapped” so I don’t get out much. My hobby is the computer although I dabbled in photography (still trying to master the GIMP) and billiards a long time ago.
My computer expertise was more in document management than actual IT but I did have to figure out why many seemed not to be able to use it properly. Since it was on our intranet, that got me interested in browsers and eventually, I got here.
