Definitely, this model did wonders for me in Gradschool, but I am wondering if anyone has tried doing this in a corporate environment? I just started my first gig at a large company. I take "walking breaks" to circle the block several times a day to clear my mind and people seem incredulous that I am not tolling at my desk. Wonder how they would feel if I was devoting 4.5 hours of my day to "fun."
