From my own experience I can say that a bad back makes you hike slower, stove-up knees keep you from wading confidently, tendinitis of the elbows buggers your casting, and a dose of giardia can send you dashing to the bushes fifteen times in an afternoon, but although none of this is fun, it's discernibly better than not fishing.
