Evidence indicates that sitting at your job all day increases your risk of mental strain as well as obesity, diabetes, heart attack and more. Simple movement may help this: get up AT LEAST once hourly and MOVE IT!! Do 10 jumping jacks (or more!); Go up and down at least one flight of stairs; Get outside and walk around your work building; Drop to the floor for 10 push-ups. You get the idea. Use your imagination, to your health!!
