Keeping track of health measurements at home is pretty simple: Step onto a scale in the bathroom, take a glucose measurement on the way out the door, or strap on a blood pressure cuff while watching television.

John Halamka, chief information officer at Beth Israel Deaconess Medical Center and HMS professor of medicine, and Joseph Kvedar, HMS associate professor of dermatology at Massachusetts General Hospital, are quoted.
