In writing his book, "Always Looking Up," Fox said he wasn't sure whether to tackle the role religion plays in happiness.
"I didn't know whether to write about it, because ... I'm not an extremely religious person. I don't ... subscribe to any particular orthodoxy. I don't attend church on a regular basis. ...
