Most people nowadays don't grow up until 30-- and there's now a new stage called "emerging adulthood" that refers to people in their 20s who still live at home

The reasons for these "emerging adults" include.... fewer blue-collar jobs, expensive housing and an increasing need for extended studies.

Experts believe the phenomenon means people in their 20s are experiencing an extended period of youth and they really don't reach adulthood until 30.
