As a subject matter expert in comic book lore and the Marvel Universe, I can provide an analysis of the question regarding the mortality of Bruce Banner, the human alter ego of the Hulk.

Bruce Banner, like any other human being, is technically mortal. However, his condition as the Hulk's alter ego adds a layer of complexity to this question. Banner has been shown to be able to survive extreme conditions that would be fatal to a normal human, such as falling from great heights or being exposed to lethal doses of radiation, due to the Hulk's regenerative abilities. However, when Banner is not transformed into the Hulk, he is as vulnerable as any other human and can die from injuries, disease, or old age.

In the Marvel comics, there have been instances where Banner has come close to death, but the Hulk's emergence has often been a saving factor. It's also important to note that Banner has been shown to have a high resistance to many types of physical damage and toxins, which further complicates his mortality.

In summary, while Bruce Banner is mortal, his connection to the Hulk and the abilities that come with it can significantly affect his ability to survive what would otherwise be fatal situations.
