Bob, I just knew you were going to say something like this.  

  Apparently we are doing it different.  
I actually suspect it has as much to do with lifestyle. Maybe the soft girlie hands of modern man.  
I can lay concrete roofing tile all day.   My friend who is a concrete contractor can shovel in the hard ground all day. If he was to do my job, his hands would be torn to pieces.  If I did his, I would have blisters on my hands.
The Paleo people never got carpel tunnel from typing either.
