Dear Barbara, I am not YET sufficiently computer literate to comment on Simon's internatonal networking ..however, RE: Lewy bodies - I have heard Dr.Roger C. Duvoisin speak on the subject. How to contact him, I know not. I have read that he recently changed or added to his affiliations. He is also involved with genetic research. I think the two subjects (LB & genetics) are interrelated. I found a quote in one of his books regarding falling and. propulsion in disturbances of balance which are the result of a " ... diminished response to an impending fall." This seemd to apply to my "falling" situation. I have impoved dramatically ... which I think is the result of a little game I play at the swimming pool. Between laps I "walk a straight line" forward and backward, using the lane-divider as a guide. It's not easy ! But I'm getting better at it and seem to be falling much less.. Mary Manfredi
