I think 60 is a little early but I would definitely force-retire them by 70 or 75. I would also set a max age for being president. There is already a min age so

I think 60 is a little early but I would definitely force-retire them by 70 or 75. I would also set a max age for being president. There is already a min age so why not a max age? But I think your point that old age doesn't make people think about the future is not correct. I don't see a difference in behavior between different generations regarding tax policy, deficits or environment.
