changed after a few hours
and there is a prof of left handedness
and here is the book he wrote
Left hand Right Hand - chris mcmanus
he ( but I repeat myself from last year but so what) wanted to estimate the lefties of yore and went around the museums looking at torques - copper and silver.
they twisted see? so it gives an idea (8%) L against 92% R
and I did a Harry Enfield - you doan wanna do THAAAT !
look at the rates of s and z hand spun wool. lefties create s spun wool strands. The strand looks essy when you look at the twist under a magnifying glass
so he did. - a few hundred thousand samples from Egypt where you all know I worked. still 8% Elisabeth Crowfoot (*)
did anyone see the bronze age stilt house on telly a few nights ago?
he Chris M even went there to see the textiles
( still 8% I think)
end of leftiness tutorial
(*) wasnt that textile expert the sister of Dorothy Crowfoot Hodgkin nobel prize winner ? Yes and daughter of the textile expert who described the first found bit of Conti Silk - v v exp Roman age silk - from Dura Europos - in I think 1926. But I digress ( again)
