I don't know the answer.
But you can ask Mynx. A married women with kids that answers all. Well, not since 2001. But you might as well try.
http://www.planetquake.com/features/mynx/ , that page has the pages in which she answered questions. I was thinking you could send an email and maybe get a reply. This is the email:
mynx@mynx.com
I hope it helps.
