As humans, and also many other mammals, we are born with a certain amount of bacteria in our bodies, in fact, we wouldn't be the way we are without our single cellular chums, we live symbiotically in harmony. It is only when we have an imbalance of these life forms that we become ill.

OUr DNA btw is also made up of fragments of bygone viruses that have not been around for centuries, yet part of their molecular structure gets incorporated in ours as a kind of inherited genetic memory. If we to encounter that virus, those with the code would fare better than those without.

I am of course summarising this heavily, and I find it all incredibly fascinating.

I personally think that I am who I am, bacteria, warts and all.
