Jaromir Jagr, the second highest scorer in NHL history, is still playing professionally at the age of 53 in his home country of the Czech Republic. He's the player/owner of the Kladno Knights. This is his 38th professional hockey season, giving him Gordie Howe like longevity. I remember when he broke in with the Penguins at the age of 18, all smiles and thrilled to be in America, and immediately helped them win back to back Stanley Cups. Amazing that he's still playing all these years later.
