People grow and mature at very different rates, so what's normal for one person is not necessarily normal for another. Bone growth stops shortly after reaching puberty, so it should have stopped around age 13. Bone growth is not possible after puberty because the growth plates disappear and harden into solid bone.
Having thin bones is not abnormal unless they are prone to breakage under circumstances where a bone should not be injured. If you have not have any bone fractures, your bones are probably normal. I developed pretty much the same way as you, although I am tall, but I have thin bones, and I looked like a 12-year old when I was a freshman in college.
This isn't so bad. I am now 50 and most people think I am 10 -15 years younger than I actually am. The only to find out if there is actually a problem is to see a doc for a panel of blood tests that include an evaluation of endocrine functions.
Your family doc can do this - make sure your doc understands your growth and development concerns so you get all the relevant tests. If there is a problem, you may have slightly low levels of estrogen.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
