[Marvel] does Bruce banner age? And if so, does the hulk? Can Bruce die of “old age” along with the hulk?

I was wondering if Bruce could die of old age? (organ failure and etc) or does he just continue to live? If Bruce where to die would the hulk also die?

On Earth 2081 (Hulk: The End), Bruce explains that his body continues to age like a normal human, but transforming into the Hulk as well as his regenerative abilities means that this process stretches into several centuries. And in that universe, Bruce does eventually succumb to a heart attack as his human body gives out. But the Hulk manages to emerge at the last moment and preserves Banner's unconscious body for himself. Leaving Hulk at last completely alone. Because if he ever transforms back, he and Bruce will instantly die. 

On the other hand, on Earth 807128 (Old Man Logan), as Bruce ages, so does Hulk. And they're both considerably weaker and show all the classic signs of old age by the time Wolverine kills Hulk from the inside out. But this may not be a natural thing, but a consequence of the radiation/madness that overtook Bruce when the world fell apart. Just as his mind snapped, his body and power also started to wear away.
