Drawing. I used to kick a ball against the ウォール over and over again (i think that might count as soccer, only solitary) but i can't really do much strenuous activity like that now.
I sorta knew that. There was really nothing else to do to pass time when your forced onto a playgroung of screaming kids. I don't even think sports matter. Guys in tights chasing a ball around while people pay to applaude sounds like a waste of time, money, and effort.
