The opposite, you want people who are older, who have lived at the different stages of life, and know what the people go through at different ages, I would prefer them at least OVER 70, Why not someone who is 90-100 -110 with all that Knowledge and Wisdom ( drawback is more likely to die), besides physical jobs are out of the question for most (Jack Lalanne is an exception 88 GOOD Fingertip Pushups Consecutively) on his 88th Birthday most 20-30 year old's can't do, but they have more life experiences, knowledge, wisdom, Read Pat Buchanan's Articles and books and on TV he is probably well into his 80's, but he has great knowledge of history and tells how it relates to current times and makes Predictions that seem outrageous at the time that wind up happening Example Catalonia would try to break off from Spain, well they tried and probably will try again, In his book suicide of a Super power he said Will the USA survive until 2025 that prediction was thought to be so Insane he was fired from MSNBC, but look at how divided the USA currently is since the Summer Riots, He also predicted that the FAR LEFT would try to Villainize Heroes like Christopher Columbus when nobody saw that coming.
He is Right Wing, but with Left Wing it would be the same people over 70 would have the most knowledge, probably why Biden got over 80 Million votes about 15-20 million more than Obama who the Media seemed to want to do well.
I think it should have to be someone over 70 with an IQ above 150 (It is an Extremely Important Job so Intelligence is Paramount) who has a great knowledge of History, Economics, Knowledge of ALL Government systems and the History of how they work in Practice, I think Japan is now more United and has lower crime than the USA, I don't know why, but I think a leader should look into the reasons and try to emulate it, I would like to see USA be more united and have less crime than Japan again.
