Obvious jokes are not funny. It makes a mockery of the story to put people in a movie just to constantly talk about how they're old. I think they should go out of their way to avoid age jokes...... It was not the fans who missed the prevalent humor. A bunch of jokes about Han Solo being older than "space dirt" will not be a service to anyone who likes Star Wars. We don't need to be "weened" off of any characters, we need to enjoy the new ones and appreciate the story arcs of all of them. We don't need to be convinced to not care about the old characters.

This 100%.

And this;

Nobody advocates hiding their ages and of course they are making new/younger characters the main focus. The only objection is to making a whole joke out of the thing

There is a big difference between Indiana Jones comedy and Star Wars. I have ZERO interest in a comedy film set in the Star Wars universe. Considering what a huge fan Abrams is of the original, I have to think we don't have to worry about a comedy or age jokes. He's keenly aware of how Lucas trashed the franchise. I suspect he'll try to right the ship.
