Jon Stewart had a segment about this talking about how these procedures can be boring as fuck, and for someone of Trump's age, it makes sense he'd snooze here and there. At the same time he talked about how the media could probably be healthier in their coverage and not treat every thing he does while sitting there as an earth-shattering event.
The thing is, Stewart knows exactly why this is a big deal, and he's somewhat guilty to perpetuating it. He led his first show back with discussions of Biden's age, even taking it into his interview into that show and really questioning Biden's fitness for the job - it's quite clear that this is a pushback on that.
Now, should we just acknowledge that it's annoying that we can only choose between two old people and instead focus on the fact that one of them wants to be a dictator? Yes, absolutely, but the media as a whole has been making a big deal about Biden's age for a long time (see: the Hur report, his mixup on the President of Egypt, numerous other stories), so it's a bit rich to pull the "this isn't Earth shattering!" card when it happens to Trump.
(Not calling you out, just a frustration with Stewart)
