It has been asked what will happen to the body of Chuck Norris when he chooses to leave this world. Similar to a saint, his body will not decompose. The does not indicate holiness, Chuck Norris's body is simply so durable that it is not edible to any form of life. Additionally he will move on to another dimension. Perhaps simply phasing into another timeline. Here he will form another physical body and continue his life in a completely alternative reality.
We have to figure that all the legends of Chuck Norris's experiences have to mean he's been around for longer than a single lifetime, yet we can determine exactly how long he's been here. Being immortal, getting tired of the dimension you live in is expected, so after approximately one human life, he vanishes into another world. We continue to live semi-peacefully post-departure.
