I don't care if it is a lifetime appointment to SC, RBG(And any SCOTUS that age) should have to undergo a mental stability test...RBG had to be given a copy of the 14th amendment,because she couldn't remember..i feel bad for her, but she is deciding cases for the entire US with flawed ability to think.if the President has to have a physical evaluation,  then shouldn't there be a test for elderly ppl in high positions?
