There is a big difference between Josh and Cam. Cam, despite the mileage, doesn't seem quite obsessed as Josh. He seems more level-headed. And as mentioned before, he has done more than most people in the world have done so far, and now he is continuing to do what got him there in the first place = this type of training. Without it we would have never even heard his name. He seems to think it's working. And it's not that crazy = It's old school.
