Hi, we've got three stories from Curiosity.com to help you get smarter in just a few minutes.

I'm Cody Goth.

And I'm Ashley Hamer.

Today you'll learn about how friendships are different in your 20s and your 30s, a secret airline

that flies non-stop to Area 51 every day. in your So Ashley, have you noticed that your friendships kind of change between your 20s and your 30s?

actually predictors of well-being later in life.

The study took place over 30 years, and participants who had more social interactions at

age 20 and higher quality social connections at age 30 reported better well-being at age 50.

A study the following year from Alco University in Finland and the University of Oxford in England

found that around age 25 is when friends start getting cut from the team. So in your early

20s men and women are more socially promiscuous making lots of friends and
