Could you define aging more closely?  It seems that most
vegitarians look old by the time they are 30.  The person who inspired me
to go paleolithic (she eats an american version of her native Mongolian
diet) has a body to die for in her 50's.  We are talking about a grandmother
who gets carded at bars.
        True, this isn't NeanderThin, but I know she eats a lot of
protien when she can get it.  (Florida is a "Right to work" state, which
means labor is cheep and unions are non-existant).
