Agreed - I was using a digitizer for many years through the 90s to early 2000's doing AutoCAD and 3D work... So, I would say that my mousing was more than any average pointing and clicking one would typically do with consuming content. I found that my muscles in my back would fall asleep / go numb and I would need to really focus on posture and take breaks to lay on a racket ball ort tennis ball between my shoulders to massage those muscles. Now I get comments about my posture being so rock solid straight up when I sit at my machine due to how conscious I was of my back. Now I just do it without thinking - but really having good posture and strong back to hold up at a machine for long hours is a must.
