" older teens are treated like younger children..." Changeofname79
I do agree but I think it is a natural progression.
My mum left school and was working at 15 (maybe even 14 but she is now dead so I cannot check that fact, my dad definitely left at 15 and was working at 15).
I think nowadays it is quite rare for kids to leave school at even 16, 17 or 18, they often stay on in education, it's a rule until 18 now (although I know some get round it).
The 'get married at 16' feels like a real red herring, who wants that for their child? Who wants to have to give permission for their child because they are legally too young to make such a decision.
I'm not great at getting stats off the internet but it looks like between 1800 and 1900, women were generally married for the first time between the ages of 20 and 22. But for marriages of opposite-sex couples, the average (mean) age for men marrying in 2016 was 37.9 years, while for women it was 35.5 years.
I am prepared to be corrected as i may not have found the best sites for stats!
But either way, we live longer! So it seems natural each stage is going to get longer. BUT in reality childhood,' in the sense we may know it, is actually getting shorter, and what is getting longer is 'teenage' years; meaning anything really from 9 or 10 or 11 to 20 or beyond!
We know brains don't finish their maturing until 25, and actually go on changing so the adult to child 'threshold' isn't necessarily a chronological one. Just a legal one. If you see what I mean.
So what some are shocked about (children still in some ways not being very responsible at 16) I am less worried about! Because we are all going to have just as many years of being responsible adults as people used to have, and them some!
