Dark Knight Rises got me thinking. Just how long COULD a superhero's career last? Putting aside those who are immortal or have healing powers, of course. Let's take "normal" athletic human superheroes for example, like Batman. How long could such a person, who spends every day fighting and running madly about, leaping off buildings and getting punched in the head, getting very little sleep, expect to keep that up before their health demands they stop?
Say you start your crime fighting career at the age of 21. Would you even make it to 40?
