Human bone is as strong as granite, relative to supporting resistance.
Would you believe a matchbox-size chunk of bone can support 18,000 pounds? Compared to concrete, human bone is four times greater in support strength.
Our skin is an organ.
Just like the liver, heart, and kidneys, our outer covering is an organ. An average man has enough skin on his body to cover approximately twenty square feet. For an average woman it is approximately seventeen square feet. Approximately 12% of our weight is from our skin. And, our skin replaces 45,000+ cells in only a few seconds. It’s constantly growing new skin and shedding old skin.
