true. mao emphasized it heavily, desu. "those whose bodies are small and frail are flippant in their behaviour. those whose skin is flabby are soft and dull in will. thus does the body influence the mind. the purpose of physical education is to strengthen: the muscles and the bones; as a result, knowledge is enhanced, the sentiments are harmonized, and the will is strengthened. the muscles and the bones belong to our body; knowledge sentiments, and will belong to our heart. when both the body and the heart are at ease, one may speak of perfect harmony. hence, physical education is nothing else but the nourishing of our lives and the gladdening of our hearts."   archive/mao/selected-works/volume-6 /mswv6_01.htm
