After puberty, the bones stop growing and the muscle cells in the body stop dividing; however, cartilage continues to grow throughout the lifespan. For this reason, Dr. Oz notes, the nose continues to get bigger with age. Notably, the earlobes also appear to get bigger, although they simply elongate with the force of gravity over time.
The onset of puberty, which is a period characterized by the achievement of fertility and sexual maturation, can vary widely from child to child. Normally girls hit puberty between the ages of 10 to 14 while boys begin puberty anywhere from 12 to 16, according to MedicineNet. Men and women reach their full heights at different ages, with most women reaching their adult heights around two years after the beginning of their first menstrual cycles. Men, on the other hand, may continue to grow up until age 20, according to HealthTap.
Adolescent girls reach puberty earlier, and are reaching their adult heights earlier than ever before, likely due to environmental and nutritional influences. In 1900, the average age for the onset of the menses was 15; by the 1990s, that age had plummeted to 12.5 years old, according to MedicineNet. Early puberty, which is known as precocious puberty, occurs more often in girls than in boys.
