For a lot of people back then the year 2000 meant only one thing: total world annihilation a.k.a. Doomsday. According to some beliefs it would have take at least 15 years for the world to reboot and for the planet to become habitable once again.
For some people this seemingly crazy notion was inspired by the exaggeration of the effects the millennium bug or more famous as the Y2K problem would have on the planet. Many were scared to death the world would come to an end just because all the computer software back then was programmed to store data by abbreviating a 4-digit year. After the millennium rolled they had to abbreviate the years in a different way which, supposedly, would cause a complete and total shutdown of all digital and non-digital systems.
This is what a Canadian named Norman Feller was convinced was about to happen. So he hid himself in his backyard bunker and remained there for more than 14 years. He had only food and books. He had no radio, no Internet and no means of communication with the outside world whatsoever. He emerged from his bunker in September last year only to discover that he was utterly wrong and the world did not end but only changed a lot.
