You can grow your intelligence

1 The brain is similar to a muscle, it changes and get stronger when you use it. 

2 The nerve cells (neurons) in the brain are connected to other nerve cells in a complicated network. When you learn new things, these connections in the brain multiply and get stronger. 

3 The more you challenge your brain to learn, the more you brain cells grow. 

4 The key to growing your brain is practice. 

5 The more a person learns, the easier it gets to learn new things because their brain ”muscles” have gotten stronger.
