This was a fascinating read. One other interesting fact about the carbon in our bodies is that the sort of diet that a person eats over their lifetime can influence the ratio of the different isotopes of carbon in their body due to different plants preferentially using carbon 12 or carbon 13 during photosynthesis. You really are what you eat.
