What about limb lengthening to make you taller? Who would qualify?

Goal-symmetric limbs. The goal of limb lengthening is to create more symmetry or functional use of the affected limb when compared to the opposite side. This is an elective surgery, and a thorough discussion regarding the risks and benefits of such surgery need to be undertaken prior to considering this option. If both lower extremities are lengthened, you would become taller.
