I didn't either.
I learned that today from reading our good family friend, Somer Love's blog.
Somer was diagnosed with CF as a toddler and somewhat miraculously just celebrated her 30th birthday.
You didn't know? I guess you didn't see the two billboards in Salt Lake City celebrating that fact!
( Somer is one popular girl!)
Years ago, most people with CF did not even make it out of their teens. Thanks to research and science people like Somer are living longer and longer, Thank God.
Somer is contributing to the cause by selling the necklace pictured above, 65 of them to be precise. The story of the necklace and the ways and means to get one are located at her magnificent blog, http://lovetobreathe.blogspot.com/2009/10/making-impact-now.html
I suggest you visit her blog, you'll be glad you did!
