Among them, the wFSH of the highest functional fitness, mFSH, would be established by the FSS in its FSSH so that the normal FSS is called a successful stress; the other kinds of wFSH, wFSHa, wFSHb, wFSHc, …, or wFSHz would be established by the FSS far from FSSH so that the dysfunctional FSS is called a chronic stress.
