Question Name: Dominant Hand
Question: Which is your dominant hand?
Type:ABCD Answers:Left;Right;Ambidextrous
Handedness is an attribute of human beings defined by their unequal distribution of fine motor skill between the left and right hands. An individual who is more dexterous with the right hand is called right-handed, and one who is more skilled with the left is said to be left-handed. A minority of people are equally skilled with both hands, and are termed ambidextrous.

Possible & Known Correlations:
- The very act of being a male may increase chance of prenatal-stress-induced-Left-handedness. There is evidance that Left handedness may be caused by prenatal stress. Male babies do experience more stress prenatally because of the testosterone in their bodies even at that early stage.
