Yet another thing to worry about...

Did you know that every so often, the earth's magnetic poles change, like from north to south? It all happens in the blink of a geologic eye, about 100 years. And, at some time in the process, there isn't any magnetic field. That is very bad. This is the barrier between us and all that radiation coming from the sun. Well, we are in one of those cycles, like, now. So why are we fussing about global warming? We're all toast anyway! Extra-crispy, at that. I just love my college education. If I couldn't laugh, I'd slit my throat.
