If you've been hyperventilating over the fact that you're 23 and still living at home with your parents, single, broke and watching re-runs of Friends then don't worry.
According to science you're not even an official adult just yet.
In a piece written in the Lancet Child & Adolescent Health journal, scientists have said that adolescence now lasts until the ripe old age of 24 - not 19 as was always the case.
Their study concludes that "rather than age 10–19 years, a definition of 10–24 years corresponds more closely to adolescent growth".
Yep... You can kinda act the maggot until 24 now.
Apparently the delay of reaching adulthood in this generation is due to people staying in education for longer, getting married older and not having children as young as previous generations.
So g'wan. Stay put in the gaff with the feet up for another few months. If scientists say it's grand...
