Recent vast progress of analytical science, especially molecular and cellular biology has produced new problem in our human society. Most scientific researchers as well as general people have hardly thought totally about our own dual existences such as own body of biological system constituted of cells as nature itself and thyself as a human including man-made spiritual existence. People live in virtual world and hardly remember own body until being taken by diseases or disorders. Gravity is one of factors to maintain our living system to be healthy, because our biological system is constructed based on at least three important conditions under gravity on the earth as follows: (1) activity-dependent system at both levels of the cell and body, (2) morpho-dynamic system constituted of the cytoskeleton and extracellular matrix as a fulcrum, and (3) self organization to keep centering their mass at both levels of the cell and body. Although researches are focusing effects of gravity on plant and animals, we should think more seriously about constitution of human beings from aspect of gravity. We propose Gravity Health Science, which will play a role to consider an essential problem to know an important axis to make principle of human beings. Space biology may contribute to characterize our human system that governs our body and mind, compared with phenomena under gravity and space. The working group for human system focuses to study a method of self-control with consciousness to organize own body and stature from brain imaging using fMRI (functional Magnetic Resonance Imaging) and NIRS (Near-InfRared Spectroscopy) and biomechanical analysis of fluctuating keeping postures, which is constituted of morpho-dynamic cell system with instability. Even only to keep posture/upper body straight against gravity, even to do deep respiration performed by diaphragm, and to do slow exercise, all of which need balance with consciousness and activate our human body system. Space Utilization should be applied for us to understand human balancing system of their bodies with consciousness, like playing Tai-Chi Chuan. These exercises may contribute maintenance of our dual system of body and mind, even under space as well as on the earth. Because we can control these muscles constituting of trunk without ground as fulcrum to develop tension in place of using fulcrum produced by imaging center of the truck, called by 'Tanden'.
