Those with sisters are happier, more optimistic, and more generous

In fact, except that you should forgive him, perhaps you should be grateful to him, and it transmits Telegrafi.

New research claims that having a sister means that you are happier and more optimistic.

The study in question has surveyed 571 persons aged 17 to 25 years on their lives and found that those who grew up with sisters are more inclined to be happy.

Apparently, sisters encourage you to be more open and communicative about your feelings, which, according to experts, promotes good mental health.

At the same time, another university study Brigham Young, who has involved 395 families with more than one child, has found that having a sister makes you even more generous. /Telegraphy/
