A brief article from ScienceDaily notes a new theory on the evolutionary causes of aging and longevity. It doesn't look like a particularly watertight theory, but that's not the important point. The important point is that more scientists are talking about aging, thinking about the root causes, and working on genetics and biochemistry related to aging. This is, at heart, a good thing. In medical science, more discussion leads to more research. More research will lead to therapies and cures. One of the early steps in invigorating any field of research is to get scientists and researchers talking and exchanging theories.
