Being Left-handed doesn’t mean youa re right-brained... so what does it mean?

▼ There have been plenty of claims about what being left-handed means, and whether it changes the type of person someone is – but the truth is something of an enigma. Myths about handedness appear year after year, but researchers have yet to uncover all of what it means to be left-handed.
So why are people left-handed? The truth is we don’t fully know that either. What we do know is that only around 10% of peopleacross the world are left-handed – but this isn’t split equally between the sexes. About 12% of men are left-handed but only  about 8% of women. Some people get very excited about the 90:10 split and wonder why we aren’t all right-handed.
But the interesting question is, why isn’t our handedness based on chance? Why isn’t it a 50:50 split? It is not due to handwriting direction, as left-handedness would be dominant in countries where their languages are written right to left, which it is not the case. Even the genetics are odd – only about 25% of childrenwho have two left-handed parentswill also be left-handed.
Being left-handed has been linked with all sorts of bad things. Poor health and early death are often associated, for example – but neither are exactly true. The latter is explained by many people in older generations being forced to switchand use their right hands. This makes it look like there are less left-handers at older ages. The former, despite being an appealing headline, is just wrong.
Positive myths are also abound. People say that left-handers are more creative, as most of them use their “right brain”. This is perhaps one of the more persistent myths about handedness and the brain. But no matter how appealing (and perhaps to the disappointment of those lefties still waiting to wake up one day with the talents of Leonardo da Vinci), the general idea that any of us use a “dominant brain side” that defines our personality and decision making is also wrong.
Brain lateralisation and handedness
It is true, however, that the brain’s right  hemisphere controls the left side of the  body, and the left hemisphere the right side – and that the hemispheres do actually have specialities. For example, language is usually processed a little bit more within the left hemisphere, and recognition of faces a little bit more within the right hemisphere. This idea that each hemisphere is specialised for some skills is known as brain lateralisation. However, the halves do not work in isolation, as a thick band of nerve fibres – called the corpus callosum – connects the two sides.
Interestingly, there are some known differences in these specialities between right-handers and left-handers. For example, it is often cited that around 95% of right-handers are “left hemisphere dominant”. This is not the same as the “left brain” claim above, it actually refers to the early findingthat most right-handers depend more on the left hemisphere for speech and language. It was assumed that the opposite would be true for lefties. But this is not the case. In fact, 70% of left-handersalso process language more in the left hemisphere. Why this number is lower, rather than reversed, is as yet unknown.
Researchers have found many other brain specialities, or “asymmetries” in addition to language. Many of these are specialised in the right hemisphere  (▪ ▪ ▪)

Very interesting. But most of the artists or creative people are left handed. Generally they are soft & kind hearted & invariable achievers.

It gives good insight on the study from the perspective of left handedness & right handedness  and also has interesting information about myths associated with left handed people.

have been trying to write with both hands...some parts of the brain make extra effort to do so. the handwriting with the other hand is not as good though surprisingly the drawing is better. Hoping to achieve more with every passing day.
