I have always been so amazed by people who can successfully do the hula hoop, it's never worked for me. I really like the idea of getting up and moving for a few minutes every hour, that is something I should definitely try. I tend to get too focused on what I'm doing and time disappears. If I am holding a book or a mouse I don't realize how much time has passed until I go to move my thumb and get a zinger. I wonder if I could set my phone to give me a beep every half hour to remind me to take a break. Today looks to be a nice day for a walk in the park, it is supposed to get up to 72!
