I am not kidding about Kimura drinking all types of animal blood. It is well documented.
During his prime he ate 7-8 bowls of rice in the morning,12 bowls of rice in the evening meal plus some fish such as red snapper and Iwashi.
One time he ate "waka-moto" a digestive enzyme, that evening he ate 17 bowls of rice. Wushijima sensei was so kind to provide free room and boarding plus stipend. Whenever he got stipend, Kimura went to the restaurant to have 100 yaki-tori (chicken on a stick) in one setting. Before the major tournament, Wushijima would take Kimura to drink turtle's (special kind) blood, presumbly to make him stronger. Banana is Kimura's most favorite fruit.
As a young kid ,Kimura drank quite a lot of carp's blood as his uncle had told him it was good for heart. True or not about the efficacy of the blood, Kimura sure had a strong heart, even though he smoked cigarettes he was very good in long distance running.
