Think about how you spent your day yesterday. If you are like most Americans, you woke up, took some time getting ready for work, walked into your garage, drove to work, sat/stood/walked at your desk for 8-10 hours, possibly stepping outdoors for a 10 or 20 minute break for lunch, got back in your car at the end of the day, drove to the gym (good for you!), then drove home, cooked dinner, ate, cleaned up, sank into the couch for a few minutes if you were lucky, and then went to bed. Does that sound like a typical day for you? How much time did you get to be outdoors?
