There are pros & cons to term limits, but I think an age limit would be an easy win. It gets you most of the same benefits with a lot less resistance. Anyone who will be over 65 when entering a position should be ineligible to be elected or appointed to that position. Judges with lifetime appointments should be forced to retire on their 65th birthday. It's a clean, easy to understand & enforce rule, and provides plenty of time for people to make a succession plan before their brains turn to mush.

72 ?
