I had a science teacher once who told our class that a human exposed to a vacuum would implode into a crumpled mass (I suppose she assumed this would happen when air rushed out of the mouth and nose, though as I recall she refused to give this or any other reason for her opinion), and who stuck to this story when I protested it wasn't the case, even though she couldn't give any reasoning to back it up. this post made me bother to look it up to make sure I was right, and in fact, it seems that implosion would not occur. i feel somewhat vindicated.

God, I hope this is a real letter. Please, please tell me it is.
