Editor's Note: Click here to listen to the new season of the CNN podcast Chasing Life with Dr. Sanjay Gupta.There is no denying or escaping this one simple but far-reaching fact: Americans are surrounded by screens.As a doctor and a journalist, but most important as a dad to teens coming of age in a screen-infused world, I'm concerned.
