In this scale we can check how much of our weight is actually not ours.
In addition to our cells, like the ones that make up muscle, blood and neurons, there are also billions of bacteria, fungi and viruses in and on our bodies. Most of these are on the skin, eyes and genitals and in the mouth and intestines, and they are part of our weight. Our mother transmits these to us while we are still in the womb and, throughout our lives, a resident population of microorganisms performs several important roles for us, such as digesting food and helping our immune system.
