Three Kilos Of Bacteria Live In You

If you think that you are the only inhabitant of your body, then you are wrong. The number of bacteria living in the human body is three times the number of its cells. But they weigh quite a bit in comparison with your skeleton, muscles and viscera, about 1-3 kg (for a person 170 cm tall and weighing 70 kg). Also, not only bacteria live in you, but also archaea, fungi, protists and viruses. Some of them do really useful things, for example, participate in digestion and protect you from disease-causing organisms and harmful substances. Others simply exist without interfering with you. Live with it now.
