If Betty can work, let her work. She's funny.
That being said, I do think that politicians should have to retire at 65. It's insane how we keep ending up with senators who are in their 80's and 90's. I don't care how sharp they are, they shouldn't be in charge of the country.
If they want to work they can go into acting. Maybe they'll land a part on Betty White's new show: "Hot in Cleveland". That's right, Betty White is a Clevelander!!!!!
