Lefties have element of surprise in sports arena: study

Growing up as the odd one out may be what gives left-handed people an advantage in the sports arena, where they have the element of surprise, said a study published Wednesday.

About one in ten people are left-handed, but in a number of sports like boxing, fencing and table tennis, they were overrepresented to the tune of about one in five, study co-author Mark Panaggio told AFP.

In baseball, more than 30 percent of athletes were southpaws -- and for the top hitters in the US major league the figure rose to 58 percent.

"Left-handers have a slight boost in their skill ability just due to inherently being left-handed," Panaggio said of the findings published in Britain's Journal of the Royal Society Interface.

The study used a mathematical model to test the assertion that hand preference arises from an evolutionary need to balance cooperation (as in hunting in groups) and competition (as in battle or sports).

"If you have a left-hander facing a right-hander, the left-hander would have spent the majority of his time competing against right-handed individuals because they are more common ... whereas the right-hander would have had very little experience against left-handers," the scientist said.

"In those type of confrontations the left-handed person should have an advantage."

However, the inverse is also true.

Only about six percent of quarterbacks in American football were left-handed, Panaggio said.

Five of the world's 120 top male golfers were left-handed, and none of the top 100 women.

"We believe that it is due to the fact that it is difficult to find equipment for them to play with," said Panaggio, of Northwestern University in Illinois.

Until well into the 20th century, schoolchildren risked beatings for writing with their left hands. The English word "sinister" derives from the Latin for left.

Yet left-handers have occupied a disproportionate place in US politics. Before Barack Obama, four of the past five US presidents were also lefties -- Gerald Ford, Ronald Reagan (who was ambidextrous), George H.W. Bush and Bill Clinton.

The study pointed out that left-handers had a higher accidental death rate.

    Treasure trove of British newsreels reveals Top Gear's ancestors

    Long after television grew to dominate American and British homes, newsreel producer British Pathé kept at it, documenting the news of the day until finally ceasing production of new short films in 1970 after 60 years of effort. Last week, all of British Pathé's 85,000 films were put online — including dozens of fascinating, rare and often weird car films that resemble nothing so much as a jet-age Top Gear.

    Nissan tests self-cleaning paint that could make car washes obsolete

    During this vile, never-ending winter, motorists had three options to keep their cars clean: Shell out on regular car washes; slave away in the cold, wind and snow washing it yourself, or screw it and just drive a dirty car. I, like many, chose the last option. But if only I'd been able to test Nissan's self-cleaning car, all my troubles would have washed away.

    I tendered my resignation without securing the next job. Here’s why I don’t mind.

    I have committed a taboo – I have tendered my resignation without securing the next job. The reactions to the announcement were varied but they all pretty much hint at a deep sense of disapproval. “Why did you do that?” It was as if I had renounced my faith. “What are you going to do from now on?” Almost as though a misfortune had incapacitated me. “What does your family have to say about it?” As if I had offered to cook for the next family dinner. I was, and still am, certain of my reasons and motivations for the resignation. However the response I received got me thinking about why people are so concerned about the gaps in their careers. The developed world evolved from an agricultural economy to an industrial economy to the service age, then to the knowledge economy in the late 1990s and 2000s marked by breakthroughs in technological innovations and competition for innovation with new products and processes that develop from the research community. According to The Work Foundation, the knowledge economy is driven by the demand for higher value added goods and services created by more sophisticated, more discerning, and better educated consumers and ...
