Hope this makes you think. If we removed all the water from our bodies, only 2% of the remaining DNA is ours. We are mostly not us.
Three to eight lbs of our body weight is bacteria, fungus, and other life forms. And in a healthy person over 80% of those serve to help keep you healthy. The average person in a third world country has up to 14,000 different species of bacteria in their gut and rarely gets an upset stomach. The average American has <5,000 species and has three to seven bouts of digestive upset annually resulting in vomiting or diarrhea. Eat more dirt, stop washing your hands with disinfectents, and forget the 5 second rule!
