很多人认为变老是一件很烦的事,让人厌倦,更令人恐惧,而年龄的增长则是人逐渐变老的重要标志。有些上了年纪的人因此拒绝过生日,在他们看来,花甲之年和七十大寿并不是什么值得庆贺的喜事,而是在通往衰老的路上又前进了一步。如果真的存在时光机器的话,他们宁愿进入机器让自己回到从前。道格拉斯·鲍威尔是美国哈佛大学专门从事人体衰老应对机制研究的医学专家,经过多年的潜心探索他发现,年龄其实并不能代表一切,当人忘记出生证明上的那些数字符号,一位八旬老人也可能返老还童。
Many people think getting older is a bothering thing, getting bored and even more frightening. And the increase of age is an important sign that people get older. Some older people, therefore, refuse to pass their birthdays, and in their view, the 60s and 70s are not a celebration of joy, but a further step on the road to aging. If there is a time machine, they would rather go into the machine and get themselves back to the past. Douglas Powell is a medical expert specializing in the mechanism of human aging response at Harvard University in the United States. After years of painstaking exploration, he found that age can not actually represent everything. When people forget about the birth certificate, an eighty-year-old also May return the rejuvenation.
