Scientists called human skin a “virtual zoo of bacteria”. Some scientists compared the diversity in the human gut to a rain forest. The human gut alone contains on average 40,000 bacterial species.
According to the Human Microbiome Project in 2007, dozens of research teams have gathered data that redefine what it means to be human. Some commentators have gone so far as to refer to the human body as a superorganism whose “whose metabolism represents a combination of microbial and human attributes.

When you descend, water pressure increases while the air in your lungs decreases. When you ascend, water pressure decreases while the air in your lungs increases. Your lungs will overstretch and rupture. Asphyxiation is the deprivation of oxygen resulting in unconsciousness or death.
