i can empathize to a certain degree. not from AD but from health limitations. twice in my life i have suffered lengthy illness. it can be very discouraging. my two philosophies are "The beginner can learn everything." & "Aspire to inspire before you expire." However i am not a medical doctor nor surgeon. i am a physicist with heavy training in electronics & materials science. i developed an interest in neuroscience about 3 or 4 yrs ago. primarily i work on nanomedicine type studies when able. i am now in the midst of the second medical leave. so keep sharing your knowledge for you have much to offer doctor! david ************************************** See what's new at http://www.aol.com ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
