In all the pics and slow-mo on the tube of Federer striking the ball. He makes no facial expressions at all. It's comes so damn effortlessly for him, like he's just practicing out there but manages to put all the energy into the ball without any sign of grimace on his face whatsoever. He flows like water while others expend twice as much energy as he does. Crazy.
