Despite the fact
that both the left and right hemispheres of your brain work together, they are
not exactly the same. Each side differs from the other slightly in its functions
and processes. While no one is totally left-brained or totally right-brained,
most people tend to favour their dominant side. Strangely, about 90 percent of
humans in all societies, even prehistoric humans, are left-brain dominant. Why
the left hemisphere should come to dominate is not clear, although scientists
believe it is linked to the left hemisphere's large role in speech and motor
tasks.

side of your brain you favour, take the Dominance
Test.
