There have been studies conducted that show that Americans are overwhelmed.  Yes...overwhelmed.  I'm just as surprised as you are.  I thought we were known for being one of the laziest countries in the world.  These studies actually show that nearly three-quarters of workers say they are stressed at work, with 25% reporting they are either “very” or “extremely” stressed.  Of course Americans are going to feel this way.  There is a huge population of full-time employees who leave their paid time off (PTO) unused.
