Thanks to William and Chris for prompot feedback on my question-- I've saved the info for future use, when folks ask---but sadly I note also that it would (as I guessed) eliminate my dear hubband, who is 81 and has early signs of dementia. I am glad that there are procedures from which others can benefit, though.
