The nature of foreign bodies or parasites in the body is only now starting to be understood by science, but it appears that our own immune systems actually use these "invaders" in surprising and beneficial ways when the body detects that other more harmful toxins are present. Disease, in this context, is a critical, normal process in our bodies. This, in turn, means that everything we understand about viruses and immunity is turned on its head.

This week, Dr. Jack and Mary detail the scientific rationale why this germ theory of disease makes no real sense, based on everything we've learned in the subsequent century of life science. Tune in to learn why the media feeds our fears and biases, and we, in turn, feed the media, and the cycle goes on and on.
