to sag or to sink

i heard once that either you are a sagger or a sinker when you get older, this means that either your face with sag or sink.  I think i will be a sagger and i think that is better than being a sinker.....except if you are a sinker, then you pump collagen into your face (which sounds very painful) and plump back up your face.  I have decided that i a sagger because my mother is a sagger, but then again my mothers idea of moisturizer was to vaseline and she has smoked most of her life.
