Notes:

  1. If the water content of the body is costed at the water supply rate, instead of as hydrogen and oxygen, the average cost would drop.
  2. Of the elements whose role in human body functioning is not understood, Rubidium is the largest quantity.
  3. Costliest element found in the human body is Ceasium which is US$ 61,800 /kg.

The objective of this post is to gain an accurate understanding of the average composition of the human body and reflect the numbers accurately. So, the post is open for discussion and comments.
