ears would increase hearing, eyes would have low-light vision, fangs would help eating, fur would keep you warm, you could increase your metabolism, strengthen your bones, tendons, joints, muscles, etc. why not add webbed hands and gills and become an Olympic swimmer? although that might be cheating. can anyone else think of any cosmetics that have practical uses?
He did say that if it was purely for appearance than no. All the things you listed were cosmetic as well as mechanical changes to the body. Changing eye color is purely cosmetic but getting a human version of cat eyes is cosmetic but also provides actual measurable changes to the body's capabilities. Also fangs don't really help eating for omnivores. They help rip and tear meat better but you sacrifice the grinding action of molars for eating plants. I guess you could try to combine both herbivore and carnivore teeth but that is pretty much what omnivores have anyway.
