I've often thought she looks more on the side of haggard too.. her face holds less fat than others at that weight I guess, it seems quite harsh sometimes, especially with that long jaw & chin. Perhaps that's another reason why some soften up just slightly as they get older, to compensate for the normal loss of fat from their faces. The extreme skinniness plus normal ageing just becomes too harsh, and combines to make them look even older than they truly are.
