How long does puberty last?
All of the other answers are wrong. Puberty is an ongoing process that lasts your life time. You get a burst of changes in your teens, but then it carries on at a more sedate pace the rest of your life. An obvious one is the spurt of hair growth out of every orrifice in men from age 50 upwards, ears, nose, bum. One that creeps up somewhere between 20s and 40s is the more manly face and features and a general broadening. When you get to the end of your teen puberty all that you have are the foundations, not the finished artical, the rest will happen quietly and you will tend to only notice it in hindsight, but it is happening. You can help it along with a healthy diet and good gym workouts.
