Dear Mr. Case: I have Parkinson's Disease. That makes me one out of an estimated one and one-half million Americans who also have PD. I write you on their behalf as well as on my own behalf. I will describe some symptoms of PD which cause those like me difficulty with the world of the keyboard and the mouse. Then I will propose an AOL billing accomodation for PD patients. As my PD has advanced and become more severe, the medication which formerly controlled my symptoms predictably has become less and less effective. This is true for all PD patients. The key word is predictably. One minute I can be typing relatively easily; the next I can be frozen, unable to move my hands or arms. This can happen in less than 15 seconds! This is called switching off. A violent, completely debilitating tremor usually accompanies this freezing. By the time I recover (swtch on) (minutes or an hour later) I get to watch a lot of screen saver. Because I am typing this off line, my freezing and tremor are no more than the everyday problems all PD patients experience. If I were on line, however, my freezing and tremor could become quite expensive. Remember, the change in my condition is both sudden and unpredictable. Question: Would it be possible for AOL to "set" my Mac from your headquarters so that after 30 or 60 seconds of dead time with no keystrokes the billing clock would stop, or perhaps run at a standby rate, until a keyboard or mouse input reactivated my computer. Put simply, could AOL give certified PD patients a "purse saver" analogous to the screen saver everyone has? I realize this might be no purse saver for AOL, but it would mean much to the many of us. This is no small matter. I am relatively "on" right now, but it has still taken me 40 minutes to type this letter off line. George M. Andes
