I know I couldn't believe it when I saw how old he was, he looks 50 max in my opinion. But all his life he's taken great care of himself.
For people around the age of 16 Chuck Norris is known for the Chuck Norris jokes, but people my age know him from his action films. I am not going to debate that he's made some crappy films, and he's a bad actor but he's made a few entertaining movies. He's also a great martial artist.
