TERM / AGE LIMIT IN OFFICE
Often times, our politicians stay in office for decades. They forget why they were elected into their office, and lose touch with their populace. They forget what they're working for and end up working against their communities, rather than helping.
Just like we have a minimum age to serve in public office, we also need an age cap. Once a politician reached the predetermined age cap, they would finish out their current term and then retire. Another route would be limiting the number of terms a political official can serve.
