Where can I find a job where when I become so old and sick that I have to practically stay in bed and require a home health aide I can still keep my job? Seriously, if we ever do have a convention if the states there needs to be an age limit and a functionality clause to prevent half dead old farts hanging on for political reasons. Any serious diagnosis, especially something like a brain tumor (McCain) or senility (Pelosi?), should mandate any congressman, senator, president, of judge be removed from office immediately.
You can add Diane Finstein on that list as well.....But Congress will never set term limits nor any of the perks they get.
