Women may not show the same association because of genetic differences or the fact that they live four years longer than men on average, the scientists believe. Mental functions decline especially rapidly in the last four years before death.
科学家们认为,女性没有显示出相同关联可能是因为遗传差异或女性平均寿命比男性长4 年。精神功能衰退在死前的最后四年尤为迅速。
According to the results, men with higher levels of facial symmetry, having faces with matching left and right sides, were less prone to mental decline between the ages of 79 and 83.
根据研究结果,男性的面部越匀称——左半边脸和右半边脸对称——在79 岁到83 岁之间精神就越不容易衰退。
Facial symmetry may be a reflection of stability in men, indicating fewer disturbances such as diseases, toxins, malnutrition or harmful genetic mutations during an individual’s development.
面部匀称可能是男性稳定性的一个体现,说明在个人成长过程中较少有疾病、毒素、营养不良或有害的基因突变等问题的困扰。
