Celebrities often get a bad rap, but recently a group of celebs came together to do something really great for a young man with a form of bone cancer. Zach Sobiech was diagnosed with cancer when he was 14 and was not given a very good prognosis. Zach has handled his diagnosis, and the knowledge that he will not beat this disease with grace and joy and love. And it helped him discover that he has a real knack for song writing. He wrote a song as a final goodbye to his family and friends, and the video for it went viral. What happened next is truly awesome.
