The Martian

by Andy Weir

An ironic death for someone with a leaky space suit: too much oxygen.

I always thought it was interesting that oxygen can kill you in high enough quantities. Though it won’t happen right away, it will mess up your lungs, your eyes, and harm your skin. We think of oxygen as being our friend. But it’s one of the nastiest, most reactive, most destructive elements in the world. If it weren’t an integral part of our biosphere and 21% of our atmosphere, it would probably be illegal to possess just due to the sheer damage it can do.
