Let's take a break from concussions and language issues for a bit and talk about a more uplifiting subject on and away from the rink.
Before going any further, take a look at this video of Brent Peterson, the former NHL player and Nashville Predators associate coach who has been undergoing experimental treatments for Parkinson's Disease. If that doesn't move you a bit, you can't be moved.
Rendered unable to walk normally -- he could only shuffle his feet -- without his medication, Peterson was suddenly on a treadmill at the Preds' practice facility on Wednesday thanks to the treatments.
His is a truly remarkable story, not just because he's a great guy (which he is), but also for the hope he gives others who suffer from Parkinson's debilitating symptoms.
