Intellectual health is the ability to learn, grow and be creative. We should be life long learners, be curious and challenge our minds.   Learning something new throughout our lives keeps our brains active. If we are not intellectually stimulated, life can become mundane and this can lead to depression. A great way to ensure intellectual health is to teach others your skills. It is important to keep learning, have hobbies, listen to music, play an instrument, visit galleries and museums, read everything you can, and play.
