All thumbs: People are either rightbrained, and tend to be more intuitive, visual and creative, or leftbrained, and are more logical. To work out which you are - and reveal your inner strengths - interlock the fingers of both hands and place one thumb on top of the other.

Those who place their right thumb on top of their left thumb tend to be left-brain dominant, and thus more analytical. Those placing their left thumb on their right tend to be right-brain dominant, and excel in visual, creative and intuitive tasks.
