I'm ~5"7, but have really long legs, so limb lengthening is out of the question (I already have a feminine figure for a guy and if I lengthen my legs I will look even more ridiculous). So I can really only lengthen my torso. My understanding is that torso or spine lengthening is not yet feasible, but eventually technology will probably allow it. What research is being done into this? And when do you think torso lengthening or spine lengthening is possible? I'm surprised there has not yet been more talk about torso lengthening, since it would have a lot of demand.
