Two parts of the human body never stop growing. Human noses and ears keep increasing in size, even when the rest of the body’s growth has stopped. Our noses and ears are unique compared to the rest of our bodies because they’re composed of soft tissue enveloped in cartilage. And it’s this soft tissue that keeps growing throughout our entire lives.
Gravity guarantees that ears will look longer as people grow older. As collagen and elastin in ears’ cartilage break down, they sag and lengthen.
Ear tissue does have the ability to regenerate, however. According to Wojciech Pawlina, all “flesh” tissue has this ability, which “you can see in cases of injury such as cuts or piercings, where the ear can heal over time.”
