I am mainly looking for an answer from someone qualified like a physician. If doctors never answer any of the questions just disregard this question and let me know that I am wasting my time. I am 17 years and 2 months old. I am currently about 6' 5.5". My father is 6'5" and my mother is 6'0". My whole family is very tall in general. I only weigh 170 pounds and doubt that I am very close to finishing puberty since I don't even need to shave and I have barely any chest hair. My father didn't reach his full height until he was in his 20's. My last significant amount of growth I can gauge is that I grew 2 inches during a 3 month stretch in the summer. Also, my wingspan is actually a bit larger than my height if that means anything. I would really appreciate a qualified physician's opinion if possible.
