Not at all.

Puleeeze!  I assume nothing.  I ask a question.  And
to the extent that it suggests a possibility, I ask if
that possibility seems reasonable.  To wit: Suppose I
culture myself some "rejuvenated" bone marrow.  By
"rejuvenated" I mean composed of cells without
shortened telomeres or nuclear or mitochondrial DNA
errors.  If I then replace my "old" bone marrow with
this "rejuvenated" marrow, is it reasonable to
suppose, theoretically, hypothetically, that I might
achieve a restoration of youthful vigor in the
functionality of my new bone marrow, and consequently
a life extension result, a re-juvenation? 

Hope that clears things up, though frankly, I thought
I was clear the first time.

Best, Jeff Davis
