For anyone wondering why Biden (or anyone else, of any age) can get details of a story wrong...

31. This is wrongly conflating two separate cognitive processes

One, misrembering, is in fact something common to people of all ages. Here is a good description from two prominent psychology researchers:

The research of Simons and others in that area focuses on the limits of our cognitive abilities, and can explain things such as Hillary "remembering" that her plane was shot at when it was in fact not, leading to accusations of lying.

The potential issue with Biden is not that, but rather something called age-related cognitive decline. Some on here try to dismiss it but it is in fact a very real thing. Unfortunately, the OP is trying to use the former to excuse what may be the latter. Saying everyone does it, or others make mistakes too is using whataboutism when it doesn't apply and does not answer questions about Biden's cognitive abilities.

The problem here if Biden is the nominee is that drumpf's cognitive ability is one area where voters are going to be looking at, and for good reason. Some will jump on and say I'm comparing the two, which is ludicrous. Biden is not rump in any way, but if there are questions about his cognitive ability it could hurt in one key area where rump is vulnerable.
