Honestly, this is the way to go. There's nothing else he can do about his age.
There is something he could do about it.
He could actually show the public that he’s still fit for office.
Canned jokes are the least convincing way of trying this, and it’s honestly kind of insulting to people who believe this is a genuine concern (which according to polling is
a lot of people!).
In another thread, someone mentioned that he’s been seen working out and biking, and I pointed out that he hasn’t been seen doing any of this since last summer. I realize the weather might not be ideal for biking, but he could at least show himself running on a treadmill or something.
I also suggested he challenge Trump to some sort of live mental fitness contest….even if Trump wouldn’t bite, maybe he could appear as a contestant on Celebrity Jeopardy or something like that.
