@live2shop - About your question relating to why some of the body parts around the abdomen seem to shift and drop down or protrude where they don't belong, my guess would be about the same as yours. It probably has something to do with age, just like everything else seems to sag when you get older.
Maybe the lack of good muscle tone is another reason. And possibly movement of body parts is more common in people who have had surgery to these parts. Anyone have other ideas?
