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

The average age of 7 1 is true. At present, I only know that my eldest sister is 78 years old, that is, the aunt who wears a white cheongsam without reading glasses. Many people think that she should be the second sister without reading glasses, but in fact, because of the rejuvenation cataract surgery, the presbyopia problem has been solved together, so she looks younger without reading glasses.
