^^ what?
I think you might be taking for what said too literal? Maybe... it's a growing concern that Japan is a very old population and people are only having 1 child maybe two...
its very interesting...
What I was saying was that as the young grow old, there are not enough new young to replace what was once there... does that make sense?
and what emi said was true too... from a marketing standpoint it goes for the younger crowd.
EDIT:
there is actually a TON of information on the aging of japan and how it is becoming a problem. the main article is on wiki:
http://en.wikipedia.org/wiki/Aging_of_Japan
you can find all the references at the bottom is you want to check sources.
