I want to say congrats to Kurt for his decision. He has a big family with lots of childern, a wife, his foundations and a church, all of whom loves him, needs him and depend upon him. And that is plenty enough to fulfill his life, for the rest of his natural life. Who wants him to risk one more concussion, a concussion that could diminish his life forever. So, good for you Kurt! Best Wishes and God Bless!
Oh, and BTW thanks for the memories!
