The virtual human is here -- how much are you willing to share about yourself with the world?

We are on the verge of another revolution in health care: deeply personalized medicine. It's the next computerized step in tailoring medical treatments and medical drugs to your specific body, your very unique anatomy, the specific ways your body works and doesn't, and your path to live your life and keep healthy. But we may soon run into problems of ethics and personal privacy that could make the recent furor over Facebook and data mining look small by comparison. Personalized health and wellness comes from the intersection of improved body-worn sensors, data science, computational physiology, individually customized health assistance and -- if necessary -- highly targeted medical treatment, all coming together at once. This dramatic health revolution is enabled by the vastly reduced cost of reading and analyzing our genomes, and of huge, cheap quantities of computer power that allow us to make more precise predictions about our future health from our genetic setup.
