Official Batman vs Superman, Bruce's age

Today we finally learned the official age of the Bruce Wayne/Batman that Ben Affleck will portray in the upcoming "Batman vs Superman", not that we ALL didn't know he was playing a Bruce around his own age. Producer Michael Uslan gave us "confirmation" of our beliefs;

“So, this [controversial superhero casting] has happened time and again, and it happened with Affleck. To go back to the original thought of Bruce Wayne in his mid-40s, I think he’s going to be extraordinary.”

Some people may ask why does Ben look in his 50s in the pictures that came out in recent days, my personal guess is to make Henry Cavill look a lot younger than Ben, in a sense making Superman the younger of the two like they would be in a world in which Batman had been doing his thing for two decades.
