Question
A 19-year-old individual, currently 168 cm tall, asks about the details of having a bone age X-ray, including the appropriate age and the associated costs. They have not undergone any related treatment and want to understand how they can grow taller again.
Answer
For a 19-year-old who is already an adult, the chance of naturally growing taller again is extremely low. However, to confirm if there is still potential for growth, one can have an X-ray taken at a hospital to assess. If the epiphyses have closed, it indicates there is no possibility of natural growth; if they have not closed, there is still a chance. The cost of the examination is around several dozen yuan. Wishing you good health.
