We use 5 % of our brains - and our brain is like a muscle in a way, it needs exercising to open different channels and networks.
In reality, this claim is 100 percent myth. We use all of our brain. The only instances where there are unused regions of the brain are those in which brain damage or disease has destroyed certain regions. The Origins of the Myth Researchers suggest that this popular urban legend has existed since at least the early 1900s. It may have been influenced by people misunderstanding or misinterpreting neurological research.

- Studies of brain damage: If 90% of the brain is normally unused, then damage to these areas should not impair performance. Instead, there is almost no area of the brain that can be damaged without loss of abilities. Even slight damage to small areas of the brain can have profound effects.
- Brain scans have shown that no matter what we're doing, our brains are always active. Some areas are more active at any one time than others, but unless we have brain damage, there is no one part of the brain that is absolutely not functioning.
- Evolution: The brain is enormously costly to the rest of the body, in terms of oxygen and nutrient consumption. It can require up to 20% of the body's energy—more than any other organ—despite making up only 2% of the human body by weight.[11][12] If 90% of it were unnecessary, there would be a large survival advantage to humans with smaller, more efficient brains. If this were true, the process of natural selection would have eliminated the inefficient brains. It is also highly unlikely that a brain with so much redundant matter would have evolved in the first place.
- Brain imaging: Technologies such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) allow the activity of the living brain to be monitored. They reveal that even during sleep, all parts of the brain show some level of activity. Only in the case of serious damage does a brain have "silent" areas.
Localization of function: Rather than acting as a single mass, the brain has distinct regions for different kinds of information processing. Decades of research have gone into mapping functions onto areas of the brain, and no function-less areas have been found.
- Microstructural analysis: In the single-unit recording technique, researchers insert a tiny electrode into the brain to monitor the activity of a single cell. If 90% of cells were unused, then this technique would have revealed that.
Neural disease: Brain cells that are not used have a tendency to degenerate. Hence if 90% of the brain were inactive, autopsy of adult brains would reveal large-scale degeneration.

I have an I.Q. tested at 170. Don't have to believe me, but it's true... You asked.
I have NO friends. I find myself having to slow my thinking down when talking to the average person, kinda like when you are talking to a child. I am not bragging, you asked, I'm just answering you.
I am married, but it too is just a hobby. I enjoy manipulating people to my bidding.
I am independently wealthy, of my own making. Making money is just a hobby to me, it is very easy to do. I can't understand why most people have trouble creating wealth.
I also stay very bored. I never officially finished High School. I was too bored, and too busy with other things. I did get my G.E.D. Made the highest score ever recorded in my State. I also have no degrees, but I am self taught in literally dozens of disciplines. I have gotten to the point in my life whee I have almost run out of things to learn.
Being very intelligent is almost a curse. I am unhappy, bored, and depressed.

You could challenge your brain by learning something different - like art / music / a language ..

Sorry, if this is off-topic.
As I see here are lots of really intelligent people.
Thank you
