Hi, Mark Hirsch I, too, look forward to being helpful...I think helping self and others are rewarded by brain chemicals...we feel good for doing good. I am involved with a small PD support group. We have not yet tried to have an exercise session. Have you a short, simple, recommended exercise that could be done? Few have done <aerobics>. The video obtained from NPF has a short portion with an actor/choreographer leading with some intent to have the <visualization> of moving and <stretching> all the body toward the goal being helpful. It seems plausible to me that many <automatic> <non-conscious> physical activity processes do not remain controllable by the brain... because the initial signal from the conscious decision normally passing to the <sub-processor> motor neurons process is defeated by lack of neurotransmitter. However, <too much> retarder neurotransmitter could block. Does your dissertation contain conjectures about possible effects of exercising as a preventive measure to PD deterioration? My conjectures include this possibility ... that <re-wiring> the motor control <on switch(es)> could be accomplished by training-produced new alternative signal circuits. I am curious about cooperation among researchers. The UPF, NPF, APDA, and many smaller organizations seem to be somewhat competitive rather than cooperative. As a researcher, do you have access to <published> information that approaches 100% of the total? Have you attended seminars relevant to exercise with PD experts? Would a <dissertation> that was actually an attempt to initiate a <database PD computer expert assimilation of current best thinking> be accepted if proposed? It seems most efficient for mankind to ultimately have a computer-resident <anatomy> resource that is available to all and that is encyclopedic. Perhaps the concept of eliminating the middlemen that would evolve if encyclopedic information in the universal library that was directly accessible by all individuals to allow <diagnosis by computer medical expert> will be suppressed by the medical and legal <professions>, but I think such a goal of making all of <expert> knowledge available to all would be empowerment that could maximize the potential of humanity. However, there is abundant evidence that altruism is not the motivation of all. I do not expect a reply to all of this. sincerely, Ron ---------------------------------------------------------------- Ronald F.
