Peter Walsh of Oprah and Clean Sweep has a theory that people who have clutter are also overweight. The relationship between a dirty house and a dirty or unhealthy body are very close and I agree with him. Most people who have unruly clutter usually give up and just let things go, just like their bodies.
Walsh claims that those people who take the time and effort to keep a clean and organized home will also be more motivated to take care of themselves and lose weight. Hopefully this theory is starting to be tested right now.
