Sure, why not?  Just because an aging process is most observable late
in life doesn't mean that it hasn't been going on throughout.  Adults may
not have neuroblasts and other early development cell types but that's
not important - it's the somatic mutations (which can happen at any age) 
that are the "aging" process of interest here. 

Besides, we're quite happy to conceptualize Werner's and other progerias 
as premature aging.  Why not other age-linked phenomenon that occur in
childhood?

PS  Andy - We're talking about aging of whole organisms here ;-)
    Good to hear from you again.
