Has to be Lance Armstrong. I had a 2.5 year battle of my own and I cannot tell you what it meant to see someone who was worse off then I was kicking @ss!! The work he does and the money he raises for the cancer community is unparrelled in my opinion. Most athletes these days are solely out for themselves, (Ricky Williams, Terrel Owens, etc) Lance Armstrongs work will hopefully benefit all of mankind one day, not just a select group of people (ie. Americans).
Just my opinion
