Why 13-17 years old are adolescents and 18-19 are adults.
You stupid uneducated idiots. Just because they had the teen thing in, their age doesn't mean they are literally teenagers. It does not make you a child if you do things or act like a child, that's just the way you act and the actions. Cause you are biologically an adult or an adolescent if you still act like a child or does kiddie things. You can still act childish after your brain is fully developed. Wow, they used to say your brain is finished developed at 18, then 21 now its MID 20s??? WHAT THE **?? AREE, THEY ARE CHANGING IT???? I am 14 years old, and I am in high school. I'm a freshman and I consider myself an adolescent/teenager. I think most people are lazy to know the differences and are likely rather older adults or some guy with no brain. I think young adults and teenagers are more mature than older adults honestly. You also need to shut up and know the difference before you say "13-17 YEARS OLDS ARE CHILDREN" and "18 AND 19 ARE STILL TEENAGERS" There isn't only children and adults, why is there such thing as infants, toddlers and 13 to 17 years olds. I think child to adult transition is just a myth and why adolescence is actually a stage. A Child/Kid means anyone who is under 13. And 4-12 years olds are considered children or kids. Adults are indeed 18 and over. A child and a kid are the same thing. Teen and Adolescent are same too! That's for all, read this before you say anything that does not make sense.
