Not Sure I Want to Think About This

The strongest bone in the body, the thigh bone, is hollow. Ounce for ounce, it has a greater pressure tolerance and bearing strength than a rod of equivalent size in cast steel. When an average adult is walking, his weight puts a downward pressure of 12,000 pounds per square inch on each thighbone. In this case, even the thinnest part of the thighbone, at 1-inch thick, supports the weight of a male African elephant.
