Does anyone know what the European or Asian statistics are?  Is age
of menarche dropping worldwide or just in North America?  I would
think that estrogen "pollution" might have something to do with it
(along with dropping sperm counts).  As for the increasing size and
artificial feeding theories, my own experience (though just one case)
is contrary to that:  late menarche, bf for only 4 months, and above
average height & weight.
