so i'm a huge fan of ANTM, and on the last two seasons there has been a big "confession" episode where one of the contestants admits to having a serious illness...this also happened on the real world san diego, when frankie admits to having MS. does this happen a lot on reality tv shows? why is this so common? do producers know? anybody know of any other instances besides these? i can't think of any...

ps: someday i will get cable and be able to watch all the rad shows on bravo...
