Yes, but that's completely irrelevant, unless you also point out that the Founding Fathers would jump for joy over the prospect of longer lifespans.\n\nSome of those Founding Fathers, including Madison & Monroe, also expected that the Constitution be reformed & revised every 20 years or so. They never imagined it to permanently dictate US law as if etched in stone. And they also might have shouted GMAFB if they saw how partisanship had paralyzed their efforts at making the Constitution become a revise-able document. Of course, they wrote the Constitution before any of the authors saw first-hand the results of politically partisan elections on the national scene.\n\n\nAgain, life span for many wasn't as short as too many people say. Look at the life spans for the Founding Fathers- pretty damned long. I and many others have ancestors from the 1600s-through the 20th century who lived into their 80s and some from the 20th who lived to the mid-90s and that means they lived through the Influenza epidemic, the Depression, austerity during WWII and generally crappy health care.\n\nIt's not about a number, it's about mental competence and some are just not 'all there', all the time. If someone is visibly confused on even an occasional basis, it's time for testing. If it happens in the person's 60s, 70s or 80s, it doesn't matter but they need to be tested at some point and it needs to start NOW.\n\nNow, Biden is warning world leaders- what's the worst that can happen? And he wants to save the world from climate change- the possibility that he thinks this is possible makes me doubt his mental competence.\n\nWRT the partisanship- members of Congress fought in the chambers and dueled with firearms when they disagreed- maybe we need to have cage matches. That would make for some good entertainment and if it proves to be popular, they could charge admission as a way to offset the budget deficit that they created.
