此前人们广泛认为,大脑在60岁之后才开始衰老,而英国科学家经过长期研究得出了一项惊人的结论,即人的大脑在45岁时就开始衰老。科学家邀请7000名年龄在45至70岁的志愿者参与研究。结果发现,年龄达到48岁时,人脑的活跃度已下降3%甚至更多。这一过程不可逆转,而且随着时间的推移,活跃度下降速度还会逐渐增快。年龄达到70岁的男性,其大脑活跃度下降近10%,而同龄的女性大脑活跃度则下降近7%。
It was previously widely believed that the brain did not begin to age after the age of 60, and a long-term study by British scientists came to the astonishing conclusion that the human brain begins to age at age 45. Scientists invited 7,000 volunteers aged 45 to 70 years to participate in the study. The results showed that at 48 years of age, the activity of the human brain has decreased by 3% or more. This process is irreversible, and as time goes by, the rate of decline in activity will gradually increase. Men aged 70 and older lost nearly 10% of their brain activity, while their female brain activity dropped nearly 7%.
