Growth in human body is really interesting
The hair on the head of a person grows 1.25 centimetres every month. Similarly, the fingernails grow 3 millimetres per month. The toe nails grow four times slower than the fingernails. Meanwhile, a healthy kid grows 2.5 inches in height every year. The cartilage in ears and nose never stop growing. While, ear ossicles, and not the eyes as per common misconception, are the only part of human body which doesn’t grow from birth to death.
