Here are a couple of things you may not know about your joints:

 By the time a fetus is four months old, its joints and limbs are in working order and ready to move.

 A newborn baby has 350 bones, many of which fuse to form the 206 bones of the adult body.

 Cartilage is 65 percent to 85 percent water. (The amount of water in your cartilage generally decreases as you get older.)

 When you run, the pressure on your knees can increase to ten times that of your body weight.

 Not a single man-made substance is more resilient, a better shock absorber, or lower in friction than cartilage.
