Do your pants hang low?

I'm working to close-of-library this evening and, since I was hungry, went forth for food after 6.  I walked behind half a dozen people who were wearing their pants below their bottoms.  I remember hearing about study that found that wearing high heeled shoes (more than 3 inches) meant that you were very unlikely to develop bad knees in old age.  I wonder what such a study will say about under-bottom-pants-wearing?  While your hips are permanently skewed, your knees are broken and your ankles give out, you don't experience chronic neck tension due to all anxiety being focussed on your behind?
