If you've watched the summer olympics you know that badminton is far more than just a casual lawn game. It is just as competitive as all the other weird sports like curling and synchronized swimming. 

This particular volley (I think it's a volley in badminton) went on for 73 shots. 73 shots! Unreal.

At the end they're both drained and the one player totally collapses on the ground. 

There can only be on winner and one loser, but man, we're all winners after watching this.
