You have never seen your own face, only reflections and pictures.
You can always see your nose.
Your tongue never sits comfortably in your mouth.
You will never feel something exactly the same way someone else does.
You can't imagine a new color.
You pick up more bacteria from biting your nails...
...than you would from licking the average toilet seat!
The heart creates enough pressure to squirt blood 30 feet!
