The maximum I play per day is four hours, and after that it is a long time sitting besides that I work in front of the computer it would be all day in front of a monitor, the meal times are respected so whatever you do if you do not have a bad performance in your digestive system, keep in mind that sitting all day wears you down slowly, always be active and do not miss the meal time, want a little greetings and good luck in the long sessions you have.
