I haven't posted on this site in over 3 years, but I've come out of hibernation to tell you that height is GENETIC. No stretching, no milk drinking, no hanging upside down like a bat, it's just plain genetics. Think about it, if you could make yourself taller, why are there so many short people in the world? Are you the only geniuses in the world who have come up with the brilliant concept of stretching to make yourself taller?
You can't stretch to make yourself taller....you want to LOOK taller? Improve your posture, stand up straight, keep your head up, wear sketchers or lugs shoes, which have about 1/2 inch of sole at the bottom, that will improve your appearance of being taller, but you can't become taller by choice.
