Renown fitness guru Mackie Shilstone, who along with trainers Freddie Roach and Naazim Richardson, is preparing Bernard Hopkins for Saturday's clash with Joe Calzaghe, says the always-in-shape Hopkins doesn't have the body of a 43-year-old. "Because he is 43 years in age, that does not necessarily equate to a performance age," says Shilstone. His age is much younger from the standpoint of performance....probably in the neighborhood of 27 to 28 years old."
