I can feel it in my bones.

Is it possible to get old over night? As last night wore on my left leg started to ache, as has seemed to be the trend recently, I figured I'd stood on it a lot recently and there's probably moisture in the air or something so nothing too much to worry about. Then, waking up this morning , every joint on my left hand side is registering some kind of pain. 

I've even been drinking more milk recently.

Perhaps it was that vitamin pill I took the other day, it may have been out of date. Or can you overdose on potatoes? The mysteries of the human body know no bounds.
