Preparing for the End of the World

I've always wondered what happens to the people who we see preparing for the end of the world on a certain date. Where do they go when the date have come and passed? What do they do? Perhaps most important of all, how do they feel? Something they believed in so much that they changed their life and spent lots of money on it, did not happen.

What happened to the Canadian man who buried old school buses and made bunkers of them to prepare for the end of the world in 1999, or was it the end of the world in 2000?
A quick Google search lets me know that he's still at it. His name is Bruce Beach and he's American but moved to Canada. He's got a very amateurish looking web pages such as this and this one, have published two books and is still preparing for the end of the world. He's even been featured on Penn & Teller's Bullshit.

Cult leader Harold Camping have changed his tune, finally, and is admitting he was wrong. How the people who believed in him and emptied their bank accounts feel now, we can only guess.
The Russian sect leader Pyotr Kuznetsov has been ruled as schizophrenic and is under compulsory psychiatric treatment. Two of his sect members died before they left the cave where they were waiting for doomsday.

There are many others that I don't remember enough detail about to find again. It's a shame, it would be interesting to see what happened to them.

Now it's time again. The 2012 Mayan Doomsday Prophesy hoax have put focus on 2012 and people are once again preparing to save themselves from the End of the World (as we know it). Bruce Breach is on the bus, and so is Patrick Geryl.

So far, Patrick Geryl estimates he's already spent more than $130,000 on his survival preparations.
...
Geryl plans to survive the turmoil in a small wooden bunker far from the nuclear radiation in South Africa, where he can live off the grid for about a year and rebuild a community with other survivors. In order to do so, he has spent years stocking up on nearly 100 survival essentials, including guns and ammunition, water purification tablets, waterproof matches, a drafting table for charting stars in the sky -- even condoms to use for carrying water.

I feel mostly sorry for them. It's insanity and no one is trying to cure them and stop them from causing emotional and/or financial harm to themselves. Then again, this is also a freedom that we as humans have. We have the right to do things, no matter how idiotic they are. Smoking comes to mind when comparing to this.
