Questions about growth spurts? -_-?

Question

1. How many times do they occur in your life?

2. When do they occur?

3. How many inches do females grow during one?

Answer 1

Well I have had them about 4 times, so it depends on the person some might not have any at all.

Up to the age of about 21 most likely, because that is when you finally stop growing and your bones "lock" in to place.

The last growth spurt I had I grew 5 inches. But another one  I had I only grew 3 inches so again it depends on the person.
