Answer 1

Growth -
In some ways, one never 'stops',. . .
Your cells are always replacing themselves.
Height? different ages for different people - it's genetic.

Answer 2

Yup, smoking will affect, in large part, how your body utilizes nutrients and hence growth.
There are many variables that determine when growth slows and stops. Genetics can influence growth rates as well as nutrition and level of exercise and activity.
Generally speaking: by 16-17 your bones have quit growing and the "growth plates" at the end of bones close.
Subject to hormonal control and nutrition, muscle mass may increase and females often develop a thicker "fat pad"or fat tissue distribution.
By 25, all body systems and organs have ceased further maturation and after 35 the body structurally and functional starts to decline : Smoking will accelerate this phase significantly: As we advance in age we actually lose stature / height due to the breakdown and compression of the spinal column and there is little to no replacement of lost muscle mass.
True, many tissues in our body continue to grow and regenerate but many do not i.e. the liver and brain although there is ever growing evidence that activity and exercise offset the aging process of the brain ( see News Week)

Answer 3

Human growth, measured in height not circumference, usually ceases anywhere from age 15 to age 25.

Factors influencing the age at which growth stops include genetics, diet and overall health.

Obviously your genetic make up is going to be important. It will dictate the age at which you begin to grow, mature and cease growing.

Diet is important. A genetic makeup that says you are going to be 6 feet tall, for example, may not come true if you are on a protein poor diet.

Also, your overall health will influence the final height. A person with some sort of pathology that intervenes in the subject's genetic predisposition and the ability to absorb nutrients is certainly going to affect the final outcome.

Answer 4

First...stop smoking. I don't know if you know this, but smoking is bad for your health. Most people stop growing taller in their early 20's. There are , of course, exceptions. I knew a guy in the Navy that after 20 grew another 12" and put on 60 lbs. He had to show I.D. to his own parents when he went home. Weird...huh?

Answer 5

Don't worry man, I'm 160 at your age but I grow to 176cm at my 24, but I don't somke, or I don't have the habit of smoking. Also I'm not expert I guess that smoke may do something to your height. So it maybe ideal if ou could stop smoking until you think you have growth to the upper limit.

Answer 6

You're 16 and you smoke? That's not good, but I can't change your mind. I think smoking does stunt growth, and yeah you do stop growing at around 20.

Answer 7

i think it depends, its possible for u to grow like 4 inches after ur 18 yrs old, but that happens rarely, i say around 20 or 21

Answer 8

well, i am told 18.. others say 21, but your nose and ears nver stop growing.. that is a fact.
