If you’re thinking of asking your beloved to marry you, make sure that you utter your declaration of love into his or her left ear. New research suggests that declarations of love, jokes, or words of anger are best remembered when they are heard through the left ear. Instructions, directions and non-emotional messages, on the other hand, have more impact on the right side.
It has to do with how your brain processes information. Although the left and right hemispheres of the brain are similar structures, they have specialized functions. The left side is more logic-based and dominant, while the right is the more imaginative side.
The right side of the brain controls the left side of the body, and vice-versa the left ear has been shown in some research to be the route to the emotional side of the brain
