Most of us have sisters, and like most people, you probably had a lot of fights when growing up at your dear old parents’ house.
Well, 90% of people were like this!

So do you remember when your sister used to tell you “me being in your life actually makes you better”?

You probably laughed your heart out when hearing that huh? But you’re not gonna laugh anymore because…

Science has finally caught up with the truth that having an older or younger sister makes your life better. So hooray for sisters!
