Is the average age of sister flowers at the ends of the earth as big as 7 1 year?

There really is. Elder sister is 78 years old. It is said that they all had cataracts, and they were all cured. Especially the elder sister, her cataract+presbyopia, was cured by a rejuvenation cataract operation. This operation can not only cure cataract, but also solve many eye problems such as presbyopia, myopia and astigmatism. Their eyes are fine, and they like dressing up and playing. They really don't look like an old man who is nearly 80 years old.
