Why rope-unlocking exercises can prevent Alzheimer’s disease

　　Find a cowhide rope about 50 cm long and as thick as chopsticks (if not available, you can use a thicker rope instead), tie 20 knots first, and then do the "rope untying exercise" according to the following procedures: first use the thumb and index finger of both hands to untie 5 knots, then use the thumb and middle finger to untie 5 knots, then use the thumb and ring finger to untie 5 knots, and finally use the thumb and little finger to untie the last 5 knots.

　　elderly This exercise can be done 2-3 times a day. As long as the practitioner persists for a long time, it can not only promote blood circulation and increase the flexibility of the fingers, but also better prevent and treat Alzheimer's disease.

　　Note: You cannot use your fingernails, only your fingertips; you can tie the knot loosely at the beginning, and then gradually tighten it to increase the difficulty.
