I never understood how anyone can bite on their nails when they're nervous. At what point does a person start doing this, and what drives them to do it? And you routinely cut your nails anyway, and it's sort of difficult to do, even if they're long. Ever try biting your nails? I don't see how it does anything. But then theres the people who use they're fingernails to rip off other fingernails. Every try doing that? I hate it, becasue you always take too much off, and you somehow expose this area of your nail that you don't want open. Why do we have fingernails anyway? Are they supposed to be weapens or something, are they just there to keep the fingertips covered? Why do we need our fingertips covered? 5 bucks says God included fingernals when he was drunk.  And finally, was I the only one who thought the term "tough as nails" meant fingernails when I was a kid?
