Mark, I did at one point notice a change in my handwriitng. I belive it was due to my anxety and analyzing everthing I did through-out the day.I was spending "all day" observing my swallowing, breathing and looking at each twitch. When I stopped, ( it was hard), working my body on manual mode and allowed my body to function on auto mode, the swallowing, breathing and handwriting returned to normal.
I suspect some is due to anxiety and some due to the occasional twitches and cramping we get in the fingers. Mike
