This actually reminds me of Tyson reciting the tale about the coward and the hero - a story Cus had told him and one that obviously stuck with him. Basically he said that "the coward and the hero both feel the same way inside ie scared, but its what one does and the other doesnt that makes all the difference". Lennox Lewis on his ring walk to the Tyson fight looked a picture of fear/nerves!!!! And his style especially in the 1st round looked that of a scared/cautious fighter. I suppose its that old chestnut - fear/nerves are natural and can make or break you depending on how you handle them.
