There is an old woman in Zhoukou, Henan Province, who became popular on the Internet because she could recite the periodic table completely. In the video, grandma is in good spirits and her pronunciation is very clear. In an interview with reporters, she said that she used to be a chemistry teacher and that's what she taught. She learned the periodic table from school, and later became a teacher to teach students the periodic table, so she remembered it so firmly. But in fact, it is very powerful to remember these things at grandma's age, because when people get old, their memory will decline accordingly, and they will forget a lot of things, and netizens all say that they have forgotten them now.

In fact, the poor memory of the elderly is also related to the body. When people get old, the body will gradually decline, so the cell metabolism function of the body will also slow down, and the brain will also run slowly. Therefore, if you want to keep a good memory at this time, you should always move your fingers. Fingers are connected to the brain, and moving your fingers can stimulate the brain and make it work. For example, when a child is born, parents will also buy some small toys for their children to exercise their hands-on ability.

Now, some old people also do some sports. For example, grandma will invite her sisters to dance square dance after dinner. Square dance has become a common exercise for the elderly now. There are also many grandfathers who accompany their grandmothers and become a beautiful scenery in the square, or sometimes jog. Sometimes when we walk in the park, we can see some old people get up early in the morning and start jogging. Because the left brain controls the right leg and the right brain controls the left leg, jogging can also play a role in exercising the brain. However, the elderly must jog in moderation, and they should not run very hard at once, which is not good for their health. They should do what they can.

Besides jogging, we often see some old people playing Tai Chi in the park. When they play Tai Chi, they will take care of their whole body, from their hands to their legs, or shake their heads frequently, because the spine is the only channel for blood supply to the brain. If they exercise regularly, they can increase the oxygen supply to the brain and reduce the accumulation of fat. Because most elderly people lose their memory when they are old, it is because of insufficient blood supply and oxygen supply. The common symptom is that you are often sleepy and can lift your legs.
