What is the value of a human life?  There is enough phosphorous in the human body to tip twenty-two hundred matches, enough iron to make a small nail, enough fat to seven make bars of soap (in some cases a few more than that); enough calcium to whitewash a chicken coop; enough sulfur to delouse a dog and enough sugar to fill a small bowl.  But, is not life worth a great deal more than a few elements from a periodic chart?
