But what about the chemicals which make up your body? Well, they’re borrowed for a fairly short period. Hydrogen, the most common chemical, was formed 13.7 billion years ago. Carbon and oxygen were made in the middle of stars 12 billion years ago. You are, in fact, stardust! But, of course, not all of the human body is human. In fact, there are few human cells, compared to bacteria - ten times fewer, in fact. Many influence health and bacteria are definitely one of them. One experiment strongly linked bacteria to well-being when a scientist attempted to raise animals in a bacteria-free environment. Many died and those that did survive needed an diet to keep them alive. It seems bacteria are a necessary part of the we enjoy.
