Given how we keep coasting along on ancient stupid laws (or even resurrecting them in certain cases - _cough AZ _cough ), I don’t think it’d be wise to start instituting short-sighted age-related laws, in the event that life extension starts to rear its head in ways that start quickly invalidating expectations of the past. The only way something like this might make sense is if it there is an objective way to actually measure cognitive ability.

Though I bet cons would fight this tooth and nail, because I have a feeling a lot of their voters and candidates might not pass such tests…
