dan, reread your first sentence and tell me if it makes sense. Proofreading is a courtesy and good-training for just about anytyhing in life.

Seriously, why should I bother composing an answer to a question that you couldn't bother to read over yourself, just to make it intelligible.

And there's no point pointing out my own errors, of which I'm sure there are many scattered here and there. I do make mistakes, but I make every effort to proofread. My dyslexia causes me to miss a few things here and there, but nothing like the above.

Rant over.

Now, to answer your question, degenerative problems would be rare, as Gargoyles heal every night. They also are not prone to many diseases that might cause these problems, for the same reason. But it's possible that a gargoyle could become deaf and/or blind in a catastrophic situation that could not be healed in one night. Take Hudson's eye, for example. And gargoyles do get older, making healing more difficult and slower.
