Is it all worth it?

Been reading quiet a bit of the things people are saying about the preparation for 2012 but the question is "Is it all really worth it?"

When you see interviews like this one:

And when you read up on the matter, basically what people are saying about 2012 is that we are going to go through a pole shift. Something that has happened before. Is this is true then there is no need to prepare physically because it won't make any difference as the damage will be that great that over 90% of the species will be exterminated on this planet.

The Mayan elders say there is hope but this seems more on a spiritual level and not a physical.

Any ideas on the matter?

Cheers,
