What is it 20 something about?

    This article by Robin Marantz Henig is basically about how young people are taking longer to go into adult life. In the 1960's and 1970's people would've been done with school, moved out with a stable job and would've got married and had children in their twenties. This is all according to what sociologists call the traditional milestones. Today all the milestones are completed when  a person is in their thirties or forties or the milestones are completed in different orders for example many people nowadays have kids before they get married.

    I admit the point of this article and knew what is about 20s. But sometimes I think why we have to rush to get married or have kid. Why we have to reach those traditional milestones before 30s? I am feeling that  in the 20s we should Travel, create, meet new people, visit old friends, take chances, re-evaluate where you are and where you want to go. After we know what actually we need, we could move forward to reach those milestones that we need.
