Britain's Strong-Arm Girl -- Miss Joan Rhodes shows how she bends a steel bar with her teeth, demonstrating the tremendous power of her jaw and neck muscles.Probably the strongest girl in Britain to-day is Miss Joan Rhodes, who recently amazed "viewers" with her feats of strength before the television cameras of the B.B.C.Miss Rhodes thinks nothing of tearing thick telephone directories in half with her hands or bending steel bars with her teeth, besides lifting two or three times her own weight.Joan is just "naturally strong" and apart from ordinary sports such as swimming, tennis etc, has never had any special physical training.
