At present, it is widely recognized useful to investigate on the aperiodic variations, just like getting out of rhythm and existing of fluctuation, in a living body. Especially remarkable among the findings so far is that some fluctuations are in living's natural states and they decrease or disappear when the vital functions do not work well. In this research, we applied nonlinear analytical methods such as chaotic, (multi)fractal and wavelet ones to many sorts of vital data (heart rate, blood pressure, ECG, EEG, fMEG) and, through the combined treatment of the results, tried to find new health indices and evaluation systems that could make clear the boundary between normal (healthy) and abnormal (ill) vital functions on the heart and the brain.
