Why Earth's Magnetic Field Might Not Flip After All

I believe in einstien,and hapgood's theory on crustal displacement during a shift.It would explain some of the 25 global extinction events.Also ice ages too.
I recommend "The Story of Earth" by Robert M. Hazen.
if that happens.. all you got to go is run a magnet from north to south on your compass and you're right again.
anybody ever had a compass that pointed south may know what i'm talking about. :/
Fine for the compass, still not good for many power grids & satellites! A total flip would affect many things!
