My Condolences to him, the family, her, you, and all friends. I know what it's like, as I have been surrounded by things like this all my life, and have lost many friends, family, and friends family. It really sucks, and though I myself do not believe in any higher beings, such as a god(s) or other, I do believe that the people who have lost their lives battling cancer, are some of the bravest people around. They put up their valiant struggles, and some of the best of them are overcome by these horrible diseases, but I am sure that wherever they may or may not go, it is better than this cruel world. They, the people who die, this mans wife, they will live on forever in the hearts of those who cared, and maybe someday, through everyone's efforts, there may be a cure, so these great people can go on living everyday lives. Again, my condolences, and thoughts, and best wishes to the family and friends.
