All in body maps

Ever notice that athletes sometimes wear medical tape on various parts of their body during competition? During the 2008 Olympic games, numerous athletes, including volleyball star Kerri Walsh, wore interesting formations of "kinesiotape" on their shoulders, knees, and backs. David Beckham and Serena Williams are also fans of the tape. Perhaps this is just because David and Serena are fashionable types - they are bored with tattoos and looking for the latest in alternative body adornment.
