You do know that the WSOP lasts 8 days straight? Each day consists of 15+ hours of sitting in a chair and reading your opponents. Yes you may not have to run a 40 yard dash but you do need to stay alert. I am not a poker player. You may want to ask TDough though he plays in the WSOP every year. Last time I checked 5 hour energy was used more in the class room and workplace than the playing field.
