Yep- I have a bad habit of writing too tersely sometimes, perhaps because I don't like to type. What it means is, each new discovery leads to more enigmas. For example, they know that PD affects mainly very special areas in the brain; but why so special? If they knew that, it might be a clue to control. Then again, it might not. Cheers, Joe J. R.
