Age Limit for Congress Members?

[JusBus91 (Justin Burcham)]

Seeing as many members of Congress are in their golden years, is it maybe time to impose an age limit for how long they can run? There is already a minimum age so why not put a maximum age, say 70 years old for example? If you are in a position of Congress and turn 70 while during your term, you can still finish out your term but then cannot run any longer beyond that. I know that age affects everyone differently but there have been a few members in the Senate as well as the House who have been seen to be less than fit to continue making decisions for the United States and I think putting a age cap on these career politicians would be beneficial to the country as a whole!
