Every 16 Days About 72% of You is Replaced

Balance is important to avoid dehydration and overhydration.

About 72% of the human body is H2O (liquid water). Every ~16 days nearly 100% of the water is exchanged in a healthy body. Heavy elements like carbon, sodium and potassium take occupancy far longer perhaps 8 months – 11 months. For example the calcium and phosphorus in bones are replaced in a dynamic crystal growth / dissolving process that will ultimately replace all bones in your body.

Other larger organs’ atomic replacement can be estimated:

• The lining in stomach and intestine every 4 days
• The Gums are replaced every 2 weeks
• The Skin replaced every 4 weeks
• The Liver replaced every 6 weeks
• The Lining of blood vessels replaced every 6 months
• The Heart replaced every 6 months
• The Surface cells of digestion, top layer cells in the digestion process from our mouth through  

   our large bowel are replaced every 5 minutes

This data was first pointed out by Dr. Paul C. Aebersold in 1953 in a landmark paper he presented to the Smithsonian Institute, “Radioisotopes – New keys to knowledge”
