In my opinion, I would rather have five extra eyes. This way, I would be able to see all around and in turn I would be able to avoid a lot of incidences like muggings because I would see the muggers from far. However, if I were to have five extra eyes, I would look like a monster and actually be a monster because a normal human being should have one set of eyes.
Five extra eyes to help me because im pretty close to legally blind right now and those would help. Also the drawback of noses is you cant just say no smelling. And the price for tissues, my sweet goodness.
