Useless Useless

<p>So I was reading a cracked.com list of useless human body parts. Things like your appendix and those glands behind your eyeballs which do nothing. I got my wondering, &quot;Do the other core four races have useless body parts too?&quot; <br /><br />Of course the Vrusk exoskeleton could be thought of this way. With internal skeletons the external one is kinda useless. <br /><br />So if they do have useless parts what consequences can they have? Thinking along the lines of burst appendixes and the like.</p>
