Look at the difference in Obama's hair from when he took office to when he left. Frankly, the job is a killer.

Coloring your hair is an easy option, you have to do it before getting elected, you dont when you are leaving it.

Maybe it’s just having teenagers.

from my perspective, the reason to consider age limits for politicians, while using Biden as an example, is not the chance that he will die in office; it's rather the chance that he won't die in office.

he's showing signs of having trouble doing a good job

As if he didn't show those signs when he took office.

Presidential age limit restricts mostly the right of the people for who to vote for. If you can't trust your people to distinguish candidates abilities to perform their duties, maybe a different political system altogether would be more appropriate. Now, when media start covering up, maybe the problem also lies elsewhere

The electoral college picks. They don't have to vote for who most the people their state wants either (although state law may punish them if they go rogue).

President is only semi democratically decided as a courtesy.

But the issue isn't his age per se, it's his capacity to do the job. This isn't about ageism.

That aside, if there's an issue with age, its having a foundation and reference points that are disconnected and out of touch.
