While growing up, i was barred by my parents from using the left hand to eat, i was scolded by the elderly when giving them something with the left hand. People don't shake with the left hand.

This trend is common all over the world, which left me wondering why it is so- Why the left hand seems to be an accursed part in one sense and vital in the other.

My question now: why is it so? Who formulated this culture ? From where did it originated?
I have often atimes confronted a lot of people with this issue, but none was able to give me a convincing answer.

To me the left hand is as important as the right and there is nothing wrong in using both equally.

U knw..wats right is right...and wahts left is left...D right speaks of gud buh d left speaks of d opposite...don't get it twisted...

Your answer is not convincing. What do you have to say about left wheel and right wheel of a car? Left leg and right leg? Left this and left that?
