Every joint in your body is slicker than a skate on ice.
As a matter of fact, your body is so well lubricated at its joints that they have only one-third the friction of a sharp skate slicing its way over a hard-frozen pond. The human body is truly amazing.
Did you know that a strand of your hair is stronger than an equal-size strand of copper or nylon?
Did you know that if you are trained, and it does take some training, your eye can pick out 17,000 different shades of color, all the way from one end of the color spectrum to the other?
Did you know that your brain can send messages through your nervous system at 315 miles an hour? That’s half the speed of sound.
Of course, if the message isn’t important, it can dawdle along at one mile an hour.
