Moderately overweight people are less likely to die than people of normal weight, a new government study indicates.  The research has found that among nearly three million people, those with an "overweight" body mass index value were less likely to die than those of normal weight.  It seems to suggest that the range of healthy values for body mass needs to be tipped alittle toward the higher end.  Finally....a study that supports my end of the story.  I know when I am at goal weight I get sicker.  I catch every little cold or cough that goes by. Now I can justify my "plumpness"- Becky
