Hope this helps. Just remember, as long as you're healthy, eating right and exercise and getting enough sleep you should be fine. Every human body is different. This weight is just the average. You might be different. Talk to a doctor and a nutritionist. They should help you find and achieve your target weight.
Depends on your build. If you are concerned have your parents make you an appointment with your Dr. If you eat heathy, feel healthy and are active you are probably fine. 167 lbs is average for your height and age. Best wishes young fellow:-)
