Ran into this when reading the newspaper. This time of year the media talks and gives advice about decluttering. With interest in resolutions, decluttering becomes a popular focus. At our house we tend to tackle something regarding clutter that's been annoying us for some time. Last year we reorganized our home office.
Well, along with articles and thoughts on decluttering, we tend to get reminded of the uncle who stacked years and years of newspapers through his house. Or some other packrat story.
Here is a link to an actual rating for clutteredness. It seems to apply to general household slovenliness, and categorizes household filth in with clutter. Makes sense to me. I felt good that we don't get past "1", but could think of places that hit "2", unfortunately. But it had never occurred to me before that there could be ratings on such things.
