The study started from the researcher's enlistment in the army, gradually probed into the inner world of the researcher. Not only was the relationship between the outer world and the researcher himself displayed, the researcher also clearly indicated the internal thoughts and subtle inner process which influenced the decision-making scenario. It is an experimental text that contains strongly autobiographic elements in the qualitative field. Through narrative epistemology, the researcher explored the real life experience that natural science could hardly investigate. From the researcher's frogman's experience, his ”scared” body, ”shocked” body, ”suffered” body, and ”frozen” body presented unique meanings, through which four levels of physical sufferings were provided: A. the voluntary physical suffering completed the self courage; B. the sudden physical suffering suggested the existence of life uncertainty; C. the unlimited physical suffering destroyed the self existence; D. the sports physical suffering stimulated the human potential. The researcher expected to provide physical and cultural research a totally different vision through this profound experiential narrative.
