Human beings have the ability to be optimistic. British and American scientists have now found the part of the brain that is responsible for optimism.

It is located in the front part of the mid-brain behind the eyes. This area provides us with positive thoughts about the future.

This discovery might give scientists a better understanding of the people who suffer from depression.
