I took an Ancient Greek philosophy class on Aristotle, and in one of his shorter novels he wrote about origin (arche) and how everything must have a beginning and an end. Aristotle argued that the beginning and end of all things were connected and not independent of one another. For me, height has always been a part of one's origin. It's not something you could change, and to a certain extent it defines your roles in society, and especially in Greek society. I think LL defies this notion. We are completely going against our physical nature by artificially growing past what we were destined to be by birth. I remember a few years back when I found this site, I was astonished by the fact that people could do this so safely.
Descartes also talked about origin and how the mind and body were separated. A lot of "modern" philosophy doesn't acknowledge the soul or that very dualism. I feel our minds have disdain for our bodies, and so now more than ever we have greater control over our bodies, with height being the ultimate "blessing" that we can change. What I have thought about recently, is that once enough people change their height, and once height can be artificially manufactured, people will perhaps become desensitized to height, and it will cease to be an advantage.
You guys should all read Ayn Rand's novel called Anthem. It's about groups of people living in a dystopia, who are all categorized by their physical traits and grouped together for purposes of simplicity. The main character, who is at fault for being noticeably taller than the rest of his "brothers," realizes that he has become so sick, that he has begun to pray for homogenization, which is the project he and his brothers have succumbed to. He eventually escapes, but the novel is about not feeling at fault for physical characteristics that you have no control over, yet oddly define you.
