I'm the kind of comic reader who demands some degree of credibility to be able to fully appreciate the stories and characters, therefore a big hobby of mine is to speculate about the scientific flaws in certain comic elements and ways to make them less implausible. One of the things I've been thinking about is: How can Wolverine regenerate pounds of flesh and other tissues as rapidly as he does? From where does he gain the nutrition to reproduce his cells at such a fast rate? Does he have to eat huge amounts of food beforehand so that he can store energy for his healing factor to work? Will he no longer be able to heal if he stops eating, and if not, where does his body get energy from? Is it some extra-dimensional source like the Hulk?
