According to science, at what age does youth end?

[White_Swan_]

Is there an article about this?

[OlderAndWiser]

This is not a matter of science because the definition of "youth" is somewhat arbitrary. At one extreme, some would say that youth ends with puberty. Some would say age 16, some would say age 18, some would say age 21, and some would say youth ends when a person attains the capacity for self-support and independent living. And the definition depends on the reason you are defining youth. Are you deciding at what age young people should be subject to the military draft? At what age they can legally drink alcohol? At what age they can validly consent to sex?

It can be 30th, I am living that situation, because I came up middle ages, everything is not same before. when I was 25-30 ages I was not thinking about everything, I was just living my life. But nowadays I am considerating everything marriage, children, working, healthy, gym, friendship.

Youth usually ends not too long after puberty finishes as 25. Though, socially speaking, you’re officially no longer “young” when you hit 30, and any point after 39 is middle aged due to the current life expectancy rate being almost 80 and that’s the halfway point.

[White_Swan_]

Puberty ends at 18.

[CupcakeTheDestroyer]

Okay, so youth ends at 18

[White_Swan_]

Of course not. Youth does not end with puberty.

[CupcakeTheDestroyer]

No, but that depends on how you’re defining youth. If you mean “too young to be taken seriously” anything below 18 falls under that category, but you need to hit at least 30 for someone to respect you without talking to them first.

[White_Swan_]

Someone who is at least 30 years old is not considered young. Not all ages below 18 are young. According to science, between 18 and 30 years old is considered a young adult. Adolescence and youth are not the same thing.

[CupcakeTheDestroyer]

You sure about that?

[CupcakeTheDestroyer]

You’re speaking from your perspective as a teen. I know I’m too old for the young people to see me as their peer, and not old enough for adults to see me as fully experienced now, but they do see me as a person. You are too old to be a child, yes. That does not mean you’re an adult

[White_Swan_]

Yes, I am sure.

No, I'm not speaking from my own perspective. According to science, biologically young people between the ages of 18 and 30 are considered adults. This is not my opinion. Why do you have to be young to say this? The scientists who say this are not young.

[White_Swan_]

Since you become a biological adult at 18, many countries have set the legal age of adulthood at 18.

[CupcakeTheDestroyer]

You know, if you wanted facts I’m not sure why you asked for opinions

[White_Swan_]

Because yesterday I saw someone saying that youth lasts until 35 years old, so that's why I asked. I know that youth and adulthood are not different and I'm not asking about that. I'm just asking when youth ends. Youth is followed by middle age. I have found no evidence that it lasts until 35 years of age and that is why I am sure that young adulthood is between 18 and 30 years of age. Because that's what the experts say.

[CupcakeTheDestroyer]

So you took someone’s opinion as fact, called it wrong, and then called every opinion that didn’t line up with what you wanted wrong as a result. Did you just want to be told you’re a young adult instead of a teenager now? I don’t get it

[White_Swan_]

No, I did not accept it as a fact that youth lasts until the age of 35. If I accepted it as a fact, I would not have asked the question. That person gave his opinion. I searched for the source, but I couldn't find it. I learned through research that young adulthood is defined by experts as the age range of 18-30, and I asked my teacher about it, and for these reasons I believed it. Youth and adolescence are not the same thing. You have misunderstood me very much. Why should I believe that young people are adults because I am young? Youth is a short period and my youth will end, so there is no point in praising young people because I am young. I believe that young people are adults not because I want to believe it, but because it has been proven by scientists. There is a period called young adulthood. Whatever age I am, I accept what my age is at that time. When I was a child, I accepted that I was a child. Being inexperienced when you are young does not mean you are an adolescent. I believed what was true, not what I wanted to believe. If it was as you say, I would believe that too because the truth doesn't change.

[CupcakeTheDestroyer]

You accepted it as an incorrect fact and did a lot more than you needed to

[White_Swan_]

This is you definition of young. The age of entering puberty has dropped a lot so it never lasts until 25 and being a teenager is not the same as being young.

[Apple1996]

25-30

[Berethor]

After 30 woman's fertility start to decline, so she not young anymore.

No clue but you’re rather close to it. I’d say once you start don’t things on your own and not relying on parents to set things up for you

[4ngelic]

around 30, that's when aging truly starts

[handsomelad70]

Thirty-five, I've heard.
