The key to being a goalie

Scientists in Canada have discovered the exact spots hockey goalies need to watch to successfully block shots. Link

It turns out that successful goalies focus their eyes on the puck. Shocking result, however as graduate student Derek Panchuk points out, "Looking at the puck seems fairly obvious, until you look at the eye movements of novice goaltenders, who scatter their gaze all over the place and have a much lower save percentage than the elite goalies." So there you have it, if you are trying to stop a puck, ball, or wrench, focus your eyes on said object.
