There are at least 25 Senators in their 70’s now. Too much at stake to let it continue.
They make Airlines Pilots Retire @ 65. Good, it is good for them it is good for the Senate. Their is a top Doctor in the MI who is No.1 in his field, I heard he gave up surgery and is now teaching only as when you reach 72ish the hands aren't as steady anymore.
65, 72, somewhere in between, if it is good for careers with lives in their hands, it is good enough for the Senate.
