Someone said :
Anyone really. I'm just interested as there could be loads of different answers. What is young?
In publishing, young adults are 12-18. Young "people" usually refers to teenagers (13-19). You might consider that age limits give different ranges of youth for different areas:
consenting to legal decisions, leaving school, marrying, voting, working, drinking, driving, being an apprentice, joining the army, being party to a contract, being a candidate to various elections or nominated to various posts, booking a holiday or flying unaccompanied, gambling, buying cigarettes or nicotine-based products, leaving home, going to prison, having sex (hopefully not in that order), partaking in jury duty or social welfare.
Some psychologists will tell you youth stops at around 40, ... Anyone under 35 is too young to be elected president of Ireland. (Give or take a year depending on whether you read the constitution in Irish or in English...)
Even if some people have referred to "young people" or "youth" in this thread, these are pointless and inoperative concepts, as far as this thread is concerned.
So if they fancy answering, so be it. But it smells like this will just bring the thread off-course. Of course.
