Oh, believe me, I do all (okay, not all) of that when I'm actually on campus. I park my car at the very back of the lot. I walk to the restroom on the other side of the building. I make sure to take the stairs at least 3-4 times/day. I'm a slug by nature, but I make myself move because I want to live a decent lifespan.You say that like it's a bad thing.<he said while rattling his chains>
Even here, take the long way to the rest room. Water breaks every hour to drink water and ignore the evil candy dispensers. Use the restroom on the 5 floors above you. Visit them all. See which one you like the best. Meet new and exciting people.
Do stand up and stretch breaks every 15 minutes. Jumping Jacks? Rip your clothes off and run around the offices twice? Very stimulating and breaks the monotony for all involved.
