A couple of years ago, I re-read "Gibt es ein Leben nach der Todesanzeige" by Ephraim Kishon. It was a short story in a collection about media, and I thought "Well, of course this book will not cover Internet, since the internet wasn't invented back then". And then I did some calculating, saw, when the book was published - and thought "SHIT, I'm old."When Avatar Book One came out, The Entropy Effect—the oldest of the old original Pocket novels—was twenty years old.
Avatar Book One came out over twenty-three years ago.
I hope the rest of you feel as old as I do.
