this occurred to me

In Frank Miller's The Dark Knight Returns (1986), Bruce Wayne puts on the Bat suit one last time to fight his greatest battles as the Caped Crusader. At the end of the four-part story, a news broadcaster notes that this "old" Batman was 55 years old. I turn 55 this year. With my gray beard and people already guessing my age as 60, I guess there's no hiding it: I'm old.
