Politics is a task that both the young and old can work on together. However, when you refuse to perform what is right and expected, it is a problem for society. Everyone is welcome to join in politics, regardless of age. However, the system is dominated by old men in my nation, and they were unable to support the youth on their own. Because of this, there are more old men than young guys in the system. Do what you were elected to do, though, whether you are young or elderly.
Once it comes to politics I don't think it is a matter of age, politics is for the old and young as long you have what it takes to serve the people, the main reason people go into politics today is just because of there own selfish reasons, either to enrich their self and family not to serve the people, which the number one suppose should be about the people, how to make life easy, to clean the tears of the people, a young man can take that position and do very well, and in the other hand make things worst than the old person that was there before, so it all depends on what they can offer. Any body that want to serve the people will come and do well, it doesn't mean if the person is older or younger.
