THAT ACHY FEELING WHEN YOU'RE SICK IS CAUSED BY YOU, NOT THE VIRUS. White blood cells are part of the body's defense system, but also cause sore throats.

One is always more stuffed than the other to keep each side adequately moistened. So you can finally stop licking the inside of your CRACKED.COM nose and grossing everyone out. — Source: Scientific Reasons for B.S Things Our Bodies Do

PAPER CUTS HURT SO MUCH BECAUSE THEY'RE THE PERFECT STORM OF PAIN. Paper cuts inflict more pain than most injuries because fingertips are full of nerve endings.
