Electric shock therapy must not be used to improve memory. This is an extremely dangerous and inhumane behavior that can cause serious irreversible damage to the human body, including but not limited to brain damage, cardiac arrest, impaired nerve function, cognitive impairment, physical pain, psychological trauma, etc., and even life-threatening. We should rely on scientific, reasonable, safe and healthy methods to improve memory, such as maintaining good living habits (adequate sleep, balanced diet, moderate exercise, etc.), cognitive training (learning new knowledge, reading, playing educational games, etc.), and mastering effective memory skills. Any illegal, dangerous and harmful means should not be tried. Please always put life safety and health first.
