Your body has about 40 trillion cells, and they all arose from a single fertilized egg. But it turns out the DNA in many of those cells is no longer a perfect clone of that original one.
A study published Thursday in the journal Science shows that our body's cells are a mosaic, with many subtle genetic variations.
It's not news that that our cells pick up mutations as we age. Some skin cells morph into moles. And scientists have previously documented widespread genetic changes in cells in the skin, esophagus and blood.

Exactly why air, water, soil pollution, is so damaging - also additives in the food that are known agents of damage like MSG and aspartame . . . and then there is GMO's which have increased the use of glyphosate in food but also stays in the soil and gets in the water. I mean if we choose to pollute our bodies that is one thing. But to be unable to avoid pollutants is an entirely different story.

What is interesting is you can take a village and separate two halves by geography and they will mutate into in their unique way.
