In case anyone is interested

 There are these free courses you can take on coursera.org.

This one seems interesting - Priciples of Obesity Economics.

It starts in October and is an online course.  A few of my friends have signed up with me, just thought I would throw it out there

Thanks for the info!! I think I'll take one of the two nutrition courses that I see on the list. What a great site!!
