Your Body is Teeming with 100 Trillion Bacteria
That's 10 times the number of human cells and they are 1/1,000th the size of a human cell. Moreover, microbes may be more important than you think:
Scientists are exploring how imbalances in friendly bacteria inside the body influence all sorts of chronic diseases….. [For example], obese people have different mixes of microbes in their intestines than thin ones….. On average, two people will have only 30% of their bacterial strains in common.
So how do I trade in my overweight person’s microbes for a thin person’s microbes?
This is why medicine needs to be personalized.
