I have 1 day left in my 6th decade. I told my kids a few years ago that they were closer to 50 than I am - depressed the heck out of them. DD is now 47, DS is 46.
Baren* - I started using an Apple at work in '81, got my first home computer (Mac) in '85. Friday I took a digitizing lesson for my embroidery machine. When we upgraded our Mac in '86, we gave the 'old' one to my folks. They joined the Mac Club in Tucson - they were in their 70s. My Mom loved Email and playing 'puter games right up into her 90s. So us 'older' folks don't have dust collecting on our brains!
