Livestrong.com is not a trusted source we can use here. Lance sold the .com address off for several million dollars. It is not run by, nor part of the foundation.org, organization. They let just about anyone author pages of info for it, and it is full of commercial content. Sorry Paul, but I have to delete that one link.
