First, does anybody know why people tend to get grumpy when they haven't eaten?
From personal experience I feel weak, get a headache and it definitely blackens my mood. Probably from a DNA hard-wired point of view the aggression is a natural reaction to starvation.
Second, why is it that songs get stuck in people's heads from time to time????
Or yawns? Why are they so contagious, even over the phone! heh
