I believe airline pilots have to retire when they rech 55. They have lives in their hands so if their minds start getting dodgy they'd be a danger. A librarian's mind can go south at 80 and no one will die because of it. Well what about a prez? Shouldn't there be CAP on the age? Maybe 65? A dodgy mind in a president can be lethal to the people. We have one right now who is what...72? But he was always dodgy. So whatcha think? Would you feel safe in a plane if the pilot were 80?
