If I could speak with Sid, I would encourage him to retire from playing... I would not wish upon anybody what concussion has done to my life. World championship, Stanley Cup and Olympic gold! Most hockey careers are not so successful and his career has been most successful. He may be symptom free now, but another knock on the noggin could leave him with more persistent symptoms. Why risk your well-being and family life? Why push your luck?

That's my thinking on the subject...
