In Netherlands, crowned-for-life monarchs step down when they feel new blood is required.
In UK, monarchs serve for life but politicians retire when it’s time for new blood.
In India, politicians rule their fiefs (states, parties, constituencies) like monarchs. They rule for life, long after they’ve become prehistoric relics and a drag on their own legacies. And when they finally go, they pass on their fiefs to their frequently inept heirs, biological or ideological.
