有一位学者说过:弹性是年轻的标志,此话有一定道理。人到中年以后,随着生理年龄的增长,各器官组织的弹性、韧性就会逐渐减弱,皮肤、肌肉、骨骼、血管会逐渐失去弹性、韧性。因此,老年人易患骨折、冠心病、脑血管等疾病。一般来说,生理上的衰老过程是难以逆转的。人至老年,健康长寿是可以争取的,但返老还童,对绝大多数人来说却只是可望不可及的幻想。白发鹤首重又须发如漆,满口牙龄落而复生的例子,恐怕只是凤毛麟角罢了。 One scholar once said that flexibility is a sign of youth. There is some truth to this remark. After middle age, with the increase of physiological age, the elasticity and toughness of various organs and tissues will gradually weaken, and the skin, muscle, bone and blood vessels will gradually lose their elasticity and toughness. Therefore, the elderly susceptible to fractures, coronary heart disease, cerebrovascular disease. In general, the physiological process of aging is difficult to reverse. People can achieve health and longevity through old age. However, rejuvenation is only an elusive fantasy for the overwhelming majority of people. White hair crane first heavy and hair should be made, such as paint, mouth full of teeth age and resurrection example, I am afraid only very rare Bale.
