Question

y do boys get moustache on their upper lip when they reach the age of adolescence

Answer 1

You all must have seen a sudden increase in height in some of your friends or you must have seen the sudden appearance of the hairy line above the lips in boys. Have you ever wondered, what are these changes all about? These are seen because your friends are growing up. Growth is a natural process that begins from the day when you were born, but upon crossing the age of 10 or 11, there is sudden growth that becomes noticeable.The period of life when the body undergoes certainly noticeable changes, leading to reproductive maturity is called adolescence. It begins after the age of 11 and lasts up to 18 to 19 years of age.
