I found this video on the allergy support forum that I belong to.  I thought it was well done and felt that you might be interested in seeing it.  You should be able to click on the link below, but if it doesn't work you can copy and paste it in your browser.

     I have added some of you to my mailing list so that when I add things to this blog that I think you might be interested in you will recieve this email to let you know.  Feel free to look at my blog whenever you wish. I welcome all comments and feedback as well.
