Do you think when Wolverine pops his claws his forearms seem lighter and kinda empty to him?

And, healing factor or not, do you think he worries about cutting the backs of his fingers?

If you cut out his heart, would it grow back?
If so, why doesn't he donate a lot of hearts?

If (back when Magneto removed his adamantium skeleton) you cut Wolverine perfectly down the middle, would each half regrow another half and then you'd have two Wolverines?

When Wolverine has been burned alive, his healing factor has returned him back to normal...

...including his haircut.

Does that mean that Wolverine ALWAYS has to have that haircut for the rest of his life?

Is that just part of him now?
