How much of my brain capacity do I use on a daily basis?

There is a myth that we only use 10% of our brain. In fact, most of us use most of our brain, most of the time. An exception to this rule would be if a part of your brain was damaged, for example. This can happen more easily than you might think, for instance, if you’ve had a severe blow to the head, or if you drink a lot but, generally speaking,
we all use most of our brain, most of the time.

Can I increase my brain, or use more of it?

The more you use your brain, the more you develop it. The more things you learn, and the more different things you do, the more you are using your brain.

At what age did my brain develop fully?

One answer to that is, it almost never is fully developed, because it’s always developing. That’s a key message: we’re always developing.
But, if you look at it in a different way, the first year of development is very rapid, any parent will tell you that! You see phenomenal changes in a child: in its behaviour, its understanding, and in the way it interacts with the world in the first year of life.

After that first year, the brain looks like the brain of a normal adult. By about three, the brain has a thousand trillion connections, that’s about twice as many as an adult. From about the age of three to 10, the child undergoes very rapid intellectual, emotional and social
development. Think about some of the children you know, and you can see it happening in them. The brain activity is huge, about twice the level of adult brain activity. Probably your brain is ‘fully developed’ around the age of 20, although women’s brains do tend to be ahead of
men’s. For men it’s more like 25.
