Fio would guess that almost every culture, past and present. has had physical games with appreciative audiences applauding their teams on to victory. The observers, of course, feel like they're out there on the playing field along with their heroes.
Sports are competition, a non-violent representation of war, and the fans are vicarious turf warriors. Maybe the Arab countries would have less political upheavals if they had more competitive sports to channel their citizens' energies.

Face-lift, here we come.
