Hello there,,,,,,,first and foremost you need to understand that every person is unique,,,also there is huge dominance of gene play which gives us our external and systemic characters,,,,,hence we have people like shaqil o neal or usain bolt with altogether different excellence and also people like sachin tendulakar who are kings in their own field.
You can try certain exercises,,,,like stretching ,climbing and a good nutritious diet,,,,however there is no established study which states that exercises helps in increasing height.
Next Steps
keep on with your active and healthy lifestyle....and dont concentrate much on your height,,,,it might increase or it might not
Health Tips
beware of teleproducts which promise to increase your height.....that is pure business and sham...
regarding surgeries...there are conflicting results and i would definately not recommend it.
Do resort back to me if you have any doubts
regards & take care
