Spreading the truth about fat: It might be good to put on a few pounds in midlife 

Middle-age spread may not be such a bad thing after all. According to a new study, it could mean you live longer

If your waistline has filled out and your jeans are feeling that bit too tight in your 50s and 60s, don't worry - it could be an indicator of longevity.

Provided you have not tipped the scales towards obesity, there is new evidence that gradually gaining a few pounds as you age might not be such a bad thing.
