Receding hairlines are good?
Well, better than your hair slowly advancing down your forehead and conquering your face (imagine having to try to shave your eyelids or nose). That said...none of those things have a scientifically plausible method for coming about (the "sneezing out" one is about as sensical as saying "it was smart of God to make poop go out of your butt instead of in", an advancing hairline wouldn't really provide anything not already provided by facial hair, etc).
Well yes, receding hair is better than it going down your face, but creating the first stages of going bald is hardly something for god to brag about.
Anyway, I just find it bizarre that they had such a hard time coming up with good examples, when there are so many truly amazing things about the world/human body, that they could have went with.
