I know barbosa talks about fighting spirit and I agree with him. I also believe he doesn't think much of Cameron's fighting spirit and I don't know if I agree or not. But I don't think you need fighting spirit for arm wrestling, just strength, speed, and technique. I don't know if those biceps on Cameron Diaz are real or manipulation of the photographs. If they are there is no way Britney would put her done in seconds. If Britney won at all it would be a long fight with her outlasting Cameron. Most likely it would be Cameron who would put Britney down in seconds, otherwise Cameron would win after a struggle.
