Can anyone indicate what is the elemental composition of an average human  
being.  I assume the principal elements are Oxygen, Carbon, Nitrogen and  
Hydrogen and traces of mineral salt elements. But I do not know in what  
percents.  I assume the highest would be O since we are made mainly of  
water (H2O).  Would someone have numbers on that or be able to indicate  
where I could find them. Thank you.
