I would have to agree and say that the show is mainly about a day in the life of Lance Armstrong. I mean it's for hard core roadies who love cycling. They are not going to air his actual training secrets and preparations, etc etc etc. Everything is going to be generalized......but hey its fun to watch.
As for the "I don't have a wife" comment, I am divorced and didn't see any problem with what he said. I don't believe that he made it sound insulting or horrible. Who knows how much of that conversation was actually edited out to begin with. It was all said in a joking manner and I agree that sometimes you have to make light of some of your worst experiences.
