1. Flexibility means that our five fingers are clenched in turn and then released in turn. This repetitive process can promote the flexibility of our fingers. We can buy a grip at home to exercise the grip strength of our hands and the strength of our fingers. It can promote the development of our brain to a certain extent and help it run faster.
2. The accuracy of the finger is whether we can accurately use it to buy a finger. The simple expression is whether we can accurately touch every note and every keyboard when playing the piano or typing, and then whether the finger has a stable strength to play and whether there is a trembling phenomenon. These are all processes that promote the development of our brains. The faster you type, the faster you play the piano, which proves that our brains react faster. Although, in the final analysis, playing the piano or typing has become a habit of the subconscious mind, that is, the subconscious mind will do it when it comes to this thing, but he will still improve the speed through our brain's exercise bit by bit at the beginning.
The development of the brain is a systematic process, which cannot be changed simply by moving your fingers. We can only say that moving our fingers can better let us take care of our lives and then keep our brains flexible enough. Usually you can keep your brain agile by exercising, doing Sudoku and reading books, which is better.
