You see it everywhere and many of us do it ourselves. Whether trying to squeeze the most out of our busy day or out of simple boredom, we talk on the phone or listen to music, news or audio books while we’re walking. The business person trying to get a little work in while going to pick up lunch, the mom or dad having a tense conversation with one of the kids or the teenager listening to her iPod on her way home from school – it’s a normal part of everyday life now.
