Eh?  i dont follow.  but i have a question: you said babies dont age
prematurely, which obvioulsy is true for the most part.  what about those
genetic defects (damn forgot the name) in which the person ages at an
accelerated rate so that they look like they are 70 when they are 7.   or
is this missing the point?  im not sure because i didnt quite follow you.

also, whose ova is a million years old?  now that i really dont understand. 
how can a person's eggs be older than they are?
