RE: This is why it's Important to Develop your Brain.

Hi, @master-mind. This is quite good. However, you didn't cite the sources of your article. You might want to add that.

The brain is an organ that serves as the center of the nervous system in all vertebrate animals.

I found a similar sentence on the Wikipedia. If you need to use the definition, you need to either quote it by adding the symbol ">" follow by space and then put the link to its source.
