耳朵到晚年才会停止生长

from 伊人耳朵SPA/一分钟耳朵SPA

我们在拿出自己小时候照片的时候,只会感觉到自己的脸在变化、眼睛在变化、鼻子在变化,但是很少有人会注意到自己的耳朵也在变化。其实,人的耳朵是一直在生长的。根据英国科学家的研究表明,人从生下来到死去,外耳确实是在一直生长的,只是生长得比较慢而已。其实,按照比例来说,刚出生的婴儿的耳朵突出来,是人来到这个世界上最大的特征了。10岁以前,人的外耳生长是非常迅速的,但是到了10岁以后,外耳的生长速度就开始放慢了,每年大约只长长0.22毫米而已。而且更让人意想不到的是人的耳垂也是一直在生长的,而且男人的耳垂比女人的耳垂长得要更加长。一直到晚年,人的耳朵才停止生长,因为它们是由骨骼和耳道构成的,会逐渐退化。
