When do most people stop growing and getting taller? i am 18 and 6 months old. do still have the possibility of growing a few more inches? is there anything i could do?

If : If you are a male, puberty usually ends by age 16 to 18 years old. However, if you began puberty late, than it is likely to end late and you have potential to grow until puberty ends. However, if your parents aren't very tall, then genetics usually says you won't be real tall either. There are no special foods, pills or extenders that will enhance your height more than nature allows.
