Hello,
In all seriousness I don't think he is building neurological pathways at all I think he is reinforcing neurological pathways long unused. When you pick up an axe to do work it is a connection to one of the strands that is at the very core of what it is to be human. Right, the axe, one of he first tools used by humans.
Forget it? All of the right actions are known, they reside in the unconsciousness carried from person to person down the generations by the DNA selected to be preserved as essential in maintaining connection and continuity to the human condition. So I say, "Away with saws and remember how to use wood."
Greetings,
Don Wagstaff
