I remember reading a few months ago about polar reversals. That wouldn't be pretty scenario.

Still, there are far more pressing issues to worry about. After all, the chance of a full reversal actually happening is pretty small.

Yep. Between this and half of the documentaries on the Discovery channel explaining how North America can blow up or we can have a giant asteroid hit the earth or dinosaurs can come back to rule the planet again and kill us all...if we spent time worrying about all of this stuff we can do nothing about, we wouldn't be able to make ourselves get out of bed in the morning.

Life is fatal. The 100% statistic is compelling.

It's happened before in human history.
