are actually targetable by this lock and key mechanism. You know, if you think about human physiology as a vast global telephone network with interacting nodes and interacting pieces, then all of our medicinal chemistry is operating on one tiny corner at the edge, the outer edge, of that network. It's like all of our pharmaceutical chemistry is a pole operator in Wichita, Kansas who is tinkering with about 10 or 15 telephone lines. So what do we do about this idea? What if we reorganized this approach? In fact, it turns out that the natural world
