Honestly, I think President Biden has a point about the demands of his job being a continuous cognitive test

Every day, he's making decisions, addressing the nation, and navigating complex international issues - that's not something you can do without a sharp mind. However, I do understand the public's concern about transparency, especially given the rigorous nature of the presidency. It might help ease some tensions if there was a standard protocol for all candidates and sitting presidents, regardless of party, to undergo some form of health and fitness evaluations, including cognitive ones. At the end of the day, what's most important is having a leader who can effectively guide the country, and age shouldn't be the sole determinant of capability.
