Today about 15 percent of the population is left-handed.But whyare people left-handed The answer is in the way the brain works.
The brain has two halves-the right half and the left half .The
right half controls the left side of the
body,and the left controls the right side of the body.So right-hanged people
have a strong left brain,and left-handed people have a strong right brain.
The two halves of the brain
are about the same size.But each side controls different things.The left side
controls language,mathematics,and logic.When you memorize the spelling of
words,or when you put things in order,you use your left side.The right side
of the brain controls your love of art,colour,
music.It is also good at recognizing faces.
This does not mean that all
artists are left-handed and all accountants are right-handed.There are
actually many exceptions.Some right-handers have a strong right brain,and
some left-handers have a strong left brain.
