I have had mine long before they were popular. I wear mine for several reasons:
1) I lost my Dad, my paternal Grandfather, and my maternal Grandmother, to cancer, and a dear friend to Lukemia.
2) My Mom has cancer.
3) The key reason I ride is to try to stay as healthy as I can and have fun doing it. Wearing the band reminds me of that fact everyday.
4) Due to my family history, I have always assumed I would die from cancer, although I read Lance's books long after wearing the band, his story was so inspiring to me, that should I get cancer in the future, I know I don't have to, and won't surrender to it.
I intend to be buried with it. (I even have spares).
