It is well known that the brain has excellent proprioception for hand motion, signals passed from hand ( muscles, joints etc) UNCONSCIOUSLY and MORE RAPIDLY than the pressure sensation that we experience as "lag pressure" ( different neurones/ different speed of conduction/ different central processors). If there are two parts of the body which are more acutely monitored by your cerebellum than the hands and the head... well, i would be amazed....and by head i include eyes.... hand eye coordination is as much henad-head coordination IMO....
Any wonder why Homer talks about the hands and head so much??
Great post, golfbulldog.
When thinking of Homer's emphasis on the Hands, I am always reminded of the Homunculus and the disproportionate amount of the brain allocated to their functioning.
