The correct answer is...

Unlike most parts of the body, the nose and ears contain cartilage, which continues to grow slowly over time. Additionally, gravity causes the skin and tissue around these areas to sag as we age, making them appear larger. While bones and muscles generally stop growing after puberty, cartilage does not, which is why your nose and ears keep growing throughout your life. This combination of continued cartilage growth and tissue sagging makes these features noticeably larger as people get older.
