I feel conflicted.
On the one hand, people should feel comfortable in their own body and who am I to have any say in this.
On the other, "short" only means something in comparison to other people. The people seeking hair transplants and Botox can just have a specific vision of themselves, they don't need "more hair/smoother skin than the average person". But you cannot feel "too small" in isolation, I think. Not that I think too highly of cosmetic surgery either way.
Maybe I'm just grasping for reasons to justify my feelings on it to myself, but I don't like this one bit.
