My last post was about medical devices in the form of adhesive patches. With sensors growing smaller and more ubiquitous in our lives, it stands to reason that we will soon be able to keep track of our vital physiological processes constantly and over a long period of time. Because we’ll have a vast data history to compare to, and because we can monitor our health constantly and in real time, health problems will be able to be spotted much earlier than is now the case. The annual physical will be antiquated. Precursors to disease will be able to be immediately recognized and preventative measures undertaken. Our medical and health infrastructure will drastically change as we move from our current emphasis of reacting to existing problems to that of initiating treatment at the earliest possible time. We will remain healthier longer and health costs will decrease significantly.
