I agree with Char, Bill, seeing the video in your msg to me allready, it is visually a sign of significant "brain-pan" IQ space - but not fat or egg-head-shaped at all... just right..and be glad its not too small, as in some pinheads I've known in personal life - who really did have VERY small heads... there is
some corrolation of brain mass to healthy normal body-mass they say, and you appear to have an enviable ratio, w/o your head looking disproportionate....lol.. I better stop trying to re-assure long enough to take my foot out of my mouth LOL....its just right, Bill. Now MY funny-looking hat size 7 3/4 still-snug head , if I were not fortunate enough - I am told by barbers - to "enviably" at 50 have a LOT of hair on my head, hides my lightbulb-shaped head I got from my Dad's head shape - just not his brains ! lol the ratio is not always indicative lol.... you have no worries on any count here Bill, having "talked" with you....
'boy he DOES have a big hea...OH wait..sorry I... I thought I had "hung up" did not hit return yet....here.. uhm... sorry LOL j/k.....
, no really.. !
