The flexibility of the brain can be improved by later exercises, such as puzzle games, thinking more, exercising more, participating in debates, speeches, improvisation and so on. The flexibility of the brain lies in its reaction speed. Although the number of nerve cells is fixed, and damaged and permanently can not be restored, but the nerve fibers to the attached nerve myelin sheath are restorable and regenerative, the human brain is relying on them to communicate with each other, interconnected, so as to ensure that the transmission of information and intake process. Targeted training yourself to play some puzzle games such as Go; more brain thinking rather than just learning from others; more physical coordination exercises; more participation in speeches and even debates; improvisation, etc., especially in childhood, can make the nerve fibers more closely linked to the activation of the brain cells in the activation of the state, to improve the flexibility of the brain.
