80 years apart

Not all babies get to see their great grandmothers when they are born into this world. Iden is one of the privileged babies to see his great grandmothers, from both his papa's and mama's side. He has 4 great grandmothers, to be exact. The average age of his 4 great grandmothers is 80 years old. Some babies will be frightened when they see old people (probably because of their white hair). But not Iden. He is willing to be carried by his great grandmothers, and can even play with them.

I suppose the word 'generation gap' does not exist in Iden's world.
