Hologram Lunch

Why is it, when you are starving at 11:30 and eat your lunch, that you (ok, I) am starving again by 12:35? Do lunches consumed before noon literally "not count"?

Also - is watching my sleeping doggie via Skypecam making me more sleepy at work? Or is it getting up at 6:30 and going running with her?

Off to supplement my lunch with another lunch.
