So what do you think of the series so far? Hair cuts aside?
And your post did get me thinking as to when hand shears/clippers were invented. I have no clue myself. Sheep have been shorn for centuries, so somebody perhaps cmae up with a smaller set for the human head after sheep shears were invented?
But of course who is to say is Mr Adams was not getting his head shaved by a barber with a straight razor on a regular basis so that would account for the even growth.
