Why 10,000 steps is a lie, and what you should do instead. (ER doctor explains)

The 10,000-step goal on your phone or watch didn't come from a scientist or a clinical trial it came from a 1960s marketing meeting. In this video, I trace where that number actually came from, walk through three major studies on steps and mortality, and show you the real number your body is asking for.
