First of all, we should always think about it, because the work and operation of our brain is based on the connection between neurons. If the connection between our neurons is broken, our brain can no longer function normally, so we can see that many people in our lives will suffer from Alzheimer's disease when they get old, which is a manifestation of the disconnection of neurons in the human brain. We can often consciously carry out critical thinking and analysis to exercise the brain and strengthen the connection between neurons.
Second, we should always do aerobic exercise. Doing more aerobic exercise is very beneficial to our brain. Studies have shown that the brain capacity of the elderly who often do aerobic exercise is much larger than that of the elderly who don't often do aerobic exercise. So people can do proper aerobic exercise when they get old, such as climbing mountains, riding bicycles, running in the morning and so on.
Third, we often dance. When it comes to dancing for the elderly, we will think of the square dance popular among middle-aged and elderly people in China. In fact, dancing is not only a recreational activity for the elderly, but also helps them to exercise their brains and delay brain aging, because the combination of dancing and music can effectively activate our brains.
Fourthly, listening to music can activate our motor cortex, auditory cortex, emotional center and limbic system. Therefore, when the elderly are free at home, they can play some music and do something else, which is convenient and effective.
