How would superheroes deal with the most challenging nemesis of all?

Getting old. Aging. The supposed golden years. Do you think Peter Parker might one day end up forgetting to wear his suit-? Would Bruce Banner be banned from all hospitals-? Would Wonder Woman still wear the same suit-?

The aging process could make either optimists or pessimists in all of us. How do you think our superheroes would adjust and adapt to it? Please mention as many superheroes if you can. Humor is most welcome. Thanks.
