Thanks Peony. Soccertese, I applaud your dedication to research over hearsay. I don't know if you had the opportunity to attend the HOPE conference in Seattle last November and to hear Dr. Alberts give the keynote speech. http://www.viddler.com/explore/nwpark/videos/13/
Happily the speech is archived at the above url. It's an hour and unfortunately the videographer didn't show the slides, but Jay explains them quite clearly. I hope this gives more credibility to what I've been writing about.

For those of you who live near Grand Haven, MI, I'll be giving a couple of talks there on April 18th. I'll post the specifics when they're in place.
