 that was the end of the debate right we we we've been subjected to a whole lot of exchanges where biden lost his train of thought or was rambling or just seemed low energy and then he gets that question about directly asked whether you're up to serve till you're 86 years old and he rambled again and and ended up not really having a particularly coherent answer or particularly sharp answer um that that was not a good good moment for biden despite the humor at the end of that that exchange that i think uh offered some rare levity in the debate
