The reality is that the current issues we face in the world are a direct result of the mode/mean age of politicians. Most people who do care interpert the core issue incorrectly anyways. It's not that we have "too many old people" that need to be replaced by younger people in general. It's that the human prime age should represent the bulk of politicians. That's mostly age 35, give or take for biological age vs chronological age and life experience. Age 35 is generally considered to be the "peak" of human physical and mental maturity. Most people are at the last stages of potential physical prime before hormone production decreases, and most people have also reached the point of existential crisis and reflection. They usually know where things went wrong in life and what they want going forward. They realize what was petty and immature. What matters and what's a waste of time. This is why 35-40 year olds should make up the vast majority of politicians. There should still be older ones, but not the majority. It's true that they often have even more wisdom, but they are also more set in their ways, and see the world through an outdated lense. 35-40 year olds are at a metaphorical peak, able to see both behind and ahead clearly. They also have the most to lose, both for their childrens' sake, their parents, and their own future. The world is far more clear and decisions seem the most important at that age. Realistically, 75% of politicians should be age 35-45. They already know this, they even tell you. The requirement to be President in the United States is age 35.
