A Question for Christians

[bluesbassman]

A related question to Christians is what, exactly, is the mental manifestation of my "soul" in the afterlife? For example, if I die completely senile from Alzheimer's at 90 years old and go to heaven, will I (or my "soul") also be senile in the afterlife? If not, at which "point" from my mortal life will my cognitive function be restored? As I was at age 21? Age 40? From my perspective, that has changed significantly over my lifetime so far.

How about those who die as newborn babies, or even before? In what sense do such souls experience an afterlife?

I suspect the answer from Christians is that our souls are cognizant in the afterlife in a way we cannot understand as living beings. However, that means the Christian (and others) beliefs once again collapse into a muck of unintelligibility upon close examination.
