Also human body contains trace amounts of other elements like silicon, manganese, fluorine, copper, zinc, arsenic and aluminium.
What is the going rate for a body's worth of these elements? One US dollar! Aren't you surprised?
Let's see if we can bump the price up a bit, tan your hide for use as leather. Your skin would be worth about $3.50 if it were sold at the price of a cow hide, which runs around $0.25 per square foot. So, if you take a dollar's worth of elements plus the value of your skin, you might be able to get $4.50, which we'll round up to $5, so you'll feel better about your chemical value.
