The ears and nose of a human never stop growing

Contrary to what we thought until now, this phenomenon is not due to the growth of the cartilage of which our ear and nose are composed, but to the Earth’s gravity. Both are composed of elastic cartilage, with great flexibility. Over time, the collagen and elastin fibers of which it is made will break down and eventually collapse under the effect of gravity. The earlobes lengthened an average of 0.22 millimeters per year, or one centimeter after 50 years.

In addition, the rest of the face, like the lips or cheeks, also lose volume, which further accentuates the contrast.
