Cool Fact of the Day
Bone is as strong as cast iron, resists bending as well as steel, but is only a third of steel's weight... And oh yeah, it's alive! See if you can create something like that! Go God!
Bone can withstand four times the weight of concrete and is only 14 percent of our total body weight!
