Political office should not be a lifelong career, so yes, politicians should have a retirement age. Sometimes they're just too old, their views are too closed.
Our politics need a couple of fresh faces, some new ideas and views. Politicians are making laws. They can't do that properly if they have health issues.
They need to understand the decisions they are making, and I feel that sometimes they just don't understand them. I don't know if it is a dementia or they are just closed to any new ideas but this is really bad for our country.
