Gathering and analyzing all this health-related data will require enormous technical and institutional efforts, which will be undertaken with a noble goal: improving the lot of humanity. But to do that, doctors must be able to turn analyzed data into treatments. ?? These treatments will be many and varied. Some are obvious. If physiological indicators suggest you have arterial plaque, analysis of your specific situation may produce a new diet and medication regimen tailored to your needs.

Consider, too, the researchers who are learning the electric language of your nervous system and building stimulators to treat such varied conditions as epilepsy, asthma, and depression. ?? There???s a long road from today???s fitness gadgets to such sophisticated medical interventions. The path won???t be straight or easy. But it will be worth the trouble.
