This is one of those threads where people demonstrate both their ignorance of history and their ignorance of life expectancy.
First, Benjamin Franklin was EXACTLY the same age as Joe Biden when he signed the Constitution. He was one of the most respected delegates. The idea that those delegates would have placed an upper age limit to political representation is laughable on its face.
But a higher life expectancy does not mean people are living longer, far from it. It means they are dying later, period. When the Constitution was signed, 40% of children died before they were 15. Today, the worldwide number, including some real shitholes, is 4%.
Ever hear of the Council of Elders? Sparta, in Ancient Greece, that legislative body had a minimum age--60. Educate yourself, look up Gerousia.
But maybe the most enlightening thing you can do, visit an old grave yard. Walk around and pay attention to the lifespans posted on the grave stones, or in my case, the markers--gravestones are prohibited.
My paternal grandparents are buried in one of those old graveyards. I go with Mom to change the flowers every three months, fake flowers but they still fade. She has to drag me out of there every time. I am walking through the oldest part looking at those lifespans. 103, 105, 109, 111. Honestly, damn near half lived over 100 years. The new part, hard to find someone that lived 100 years.
Now, maybe it is the water. I work with the public, sometimes I will meet someone accompanying their parent. This is my mom, she is 95. I will respond with, "Oh, she must live in Vale", that is Vale, NC. At least half the time I am right. And when they show their surprise I tell them, "It is the water". And yeah, I live in Vale, NC.
Like I said, life expectancy increased because people died later, not because people live longer. People don't live as long as they used to.
