Holy moly. I see people doing far...far...far more strenuous activity all day long than that.
Good lord. My utter astonishment that there are people in the world who think holding their arms in front of them between breaks and lunch for a work day is huge!
I watch guys standing next to large diameter pipes with their welding leads held out in front of them for most of the day, only putting it down to pick up the heavier grinder to finish the weld before moving on to the next one...
and I am pretty sure that holding my arms out in front of me with empty hands all day would be easier.
And I am thinking that if that wore me out...I could move my monitor and my LEAP back far enough on my desk to rest my elbows on the desk and still properly utilize the device.
LOL...C'mon, guys.
