Throw away tests that haven't failed in a year. That just a ridiculous point IMO. Written properly tests act as perfect docimentation for the system. So just because a screen or a process hasn't changed in a year, so therefore the tests have been consistently passing does not mean you throw the tests away! You never know when someone will need to maintain that piece of the system.
