A quick visit to the website showed a large index of athletes and some of the adversities they have had to overcome such as:
Jon Lester (cancer)
Jim Calhoun (cancer)
Jerome Bettis (asthma)
Mark Spitz (high cholesterol)
Bruce Jenner (ADD & dyslexia)
Greg Louganis (HIV)
There are also other celebrities outside of athletes as well as a diverse group of people battling a variety of diseases. I found the website and videos to be fascinating (talking about the athletic history), informational (because they gave great detail about each disease and how it is treated) and inspirational (hearing and reading about how so many have overcome).
