I keep having this little revelation, when I see recent photos of actors I've grown up watching:
"Man, they're getting old.
Wait a minute... that means I'm getting old..."
If you had told 11 year old me when I was starting out that one day I would own a computer I would have been wowed, at the time we were making a long distance call to a university mainframe, using a teletype machine with a papertape reader to program it. If you had told me that I would end up with some many that I had to break out the label printer to keep track of what each one was doing, and which button on the KVM was which machine, I would not have believed you.
