I think the other side will call a maximum age arbitrary, but that misses how institutions work. We already set age floors and mandatory retirement for pilots, judges, and soldiers because high-stakes roles carry cognitive and health risks. Politics is no different. A cap is not an insult to wisdom; it is a structural safeguard against prolonged power, generational lock, and decline that voters cannot reliably assess. Elections are skewed by incumbency and name recognition, so the ballot alone is a weak check. An imperfect line is better than none.
