How many players just play poker with their mouse, keyboard and mouse or game controller?

Reason I bring up this question is I normally play poker with all my hotkeys bound to my mouse, it has around 30 buttons on it lol so that with table ninja is like heaven.  The psychology plays in when I was on the jon thinking about poker while smoking(added for humor), but seriously happened at that moment. In my younger years I played video games competitively, mostly pc game which required me to use a mouse and keyboard. When I played matches I was always in a state of alert and focus. while playing poker, although I was still in a state of focus, would always end up burning out at some point or another. It dawned on me that while at my pc the only times I ever solely used a mouse was when I was browsing the web, like Facebook etc... and during those periods I'm in a state of relax. Which could possibly be a reason for the lack of concentration when I get deeper into a session. My body habit naturally relaxes while i'm only using my mouse at the pc, vs when i actively use both hands. When I play games I can play for hours on end before getting tired even though its still grinding toons to the max lvl, yet when i play poker which is just as fun I lose the concentration over a course of time. This is just a theory, I decided to rebind all my keys and give it a go. Would like any input on your thoughts and opinions as well.
