We are joined by Evan Matthews, Assistant Professor of Exercise Science and Physical Education at Montclair State to discuss benefits and risks of popular smartwatches and Fitbit bands. These trendy gadgets offer us new ways to monitor and improve self-health. Anyone of any age can have a "personal health assistant" that tracks and uses vital information to promote a healthier lifestyle. But are there risks of storing all of this personal data? Exercise scientist Evan Matthews discusses health benefits and potential disadvantages to personal health trackers. Matthews is a cardiovascular physiologist who has helped launch new publications in his field.
