I would like to get a reasonably good intuition in regards to the total amount of compound DNA from human bodies at different biochemical states, in different locations around the world (different climates). By "compound DNA" I mean, including DNA of bacterium, fungi and viruses living within one's body. For instance, gut bacteria acquired and maintained based on food intake and environmental influence.
