14. well actually I have seen some of those changes too
but they don't seem all that significant. Yes, our first TV was black and white and we had a big metal antenna on top of our house and a device that would turn the antenna for better reception (which we used and it seemed to work). Computers were pretty primitive when I was in high school and even in college I was learning on macros. The micos we had at the Air Force in late 1985 were also very primitve. 320 K floppy disks and the little red light and grinding sound when you accessed them.
None of that seems quite a significant as flying, driving, electrical devices. Cell phones to me still seem like a great evil. I was, however, slow to accept the internet too.
