That still doesn't undo my statement. Whatever you come up with is speculation & is irrelivent--you're not Kishi & regardless the series is done. It's like saying Gohan will have 100 babies simply because it's possible for him to breed.
Ok i make more simple, never was it stated having RSM, tailed beast, Hagoromo or Ashura chakra make someone immortal.
Naruto isn't immortal.
As for Gohan having kids that is something Gohan is capable of, we see in GT Gohan only has 1 kid nothing more.
Can gohan have more than 1 yes, will Gohan have more doesn't look like it.
