At what age does your body stop developing?
Never. Once you stop developing the things that make you an adult, you start developing fine lines, which develop into wrinkles. Then the gray hair develops, and the kidney stones, and the heart disease, etc. and so on.
It's different for every person. Usually though it starts around twelve it thirteen...
When we start growing sideways rather than up. :)
I don't think 18 because I'm 18 and I look about 14. And if that's true I guess I'm looking 14 my whole life.
Your body stops developing when you are around 25 - 30 years of age
Some things like ears never stop growing.
24-30 and then when you hit the age around 43-55 you start changing again. sources: Doctor
