It is almost impossible not to have microbes living on and inside us. Almost from the moment we're born, bacteria enter our gut and live there for the rest of our lives. They assist us greatly with digesting a lot of our food, particularly plants, and the gas they produce is the reason why we have flatulence! Our skin, particularly warm and moist areas such as the feet, armpits and groin are likely to have fungus and bacteria living there too. Most of these aren't particularly harmful to us, so it's no bother having them there.

It's also important to remember that if we have these 'good' microbes living on and in us, then there's no room for the 'bad' microbes to grow, which is another very significant reason why we want them.
