Isaac Newton and Housework, or Who am I to Argue with the Law?

A body at rest tends to stay at rest; a body in motion tends to stay in motion.

This is a common paraphrasing of Newton's First Law of Motion, which actually states: "The velocity of a body remains constant unless the body is acted upon by an external force."

Who knew that physics could so easily explain why I would rather lie under my warm covers, reading, than clean house? And to think Physics was my least favorite subject (PE ran a close second...)
