Dowager's hump: An abnormal outward curvature of the vertebrae of upper back. Compression of the front (anterior) portion of the involved vertebrae leads to forward bending of the spine (kyphosis) and creates a hump at the upper back
I find that the only reason I don't fall backwards is because my Dougars hump is offset (or balanced) by my banana chin. I am lucky that I have a Dougar Banana.
