Ambidextrous people have the ability to use both hands with equal dexterity. But the ambidextrous probably
prefer to write with their right hands, since lefties always smudge what they've written as they drag their hand across the page.

Children who can write with both hands are more likely to suffer from mental health problems and have difficulties in school, a new study shows.
They are twice as likely to be hyperactive as their classmates, researchers found.
They are also twice as likely to suffer from language problems, such as dyslexia.
Scientists believe that differences in how the children’s brains work compared to others could link the problems, but admit they do not yet understand how.
An estimated 600,000 people on Britain are thought to be ambidextrous, or mixed-handed, as it is also known.
Dr Alina Rodriguez, from Imperial College London, who led the study, said: "Mixed-handedness is intriguing – we don't know why some people prefer to make use of both hands when most people use only one.
She added: “Our results should not be taken to mean that all children who are mixed-handed will have problems at school or develop ADHD.
“We found that mixed-handed children and adolescents were at a higher risk of having certain problems, but we'd like to stress that most of the mixed-handed children we followed didn't have any of these difficulties."
The study looked at almost 8,000 children, 87 of whom used both hands to write.
The researchers found that by the ages of seven or eight those children were twice as likely as their right-handed peers to have difficulties with language and to perform badly in school.
By the time they reached the age of 15 or 16 the teenagers were also as likely to suffer from attention deficit hyperactivity disorder (ADHD).
Youngsters who were ambidextrous were also more likely to have more severe symptoms of the condition than right-handed children.
