世界卫生组织(WHO)指出:健康的一半是心理健康,衰老的一半是心理衰老。老年人的生理衰老显于外,一目了然,如白发、皮肤上的皱纹和老年斑等。老年人的心理衰老潜于内,须从如下几方面加以观察和分析:其一,思维。思维的速度,即思维的敏捷性变慢(但思维的深度和广度仍良好,思维的准确性和判断力及其运用经验的能力并不减退)。 The World Health Organization (WHO) pointed out: Half of the health is mental health, half of aging is mental aging. Physiological aging in the elderly is obvious, at a glance, such as white hair, skin wrinkles and age spots. The psychological aging of the elderly latent inside, to be observed and analyzed from the following aspects: First, thinking. The speed of thinking, that is, the agility of thinking slows down (but the depth and breadth of thinking are still good, the accuracy and judgment of thinking, and its ability to apply experience do not diminish.)
