For those lefties like me among us! I love the part about lefties trouble in finding a marriage partner!
FOXNews.com - Study: Number of Left-Handed People Increasing in Britain - Science News | Current Articles
Lefties have been bouncing back in recent decades following a decline in the beginning of the 20th century, a new study shows.
While lefties currently make up about 11 percent of the population, earlier studies found only 3 percent of those born in 1900 were left-handed. These claims led Ian Christopher McManus of the University College London and his colleagues to learn more about this change.
The most likely reason that lefties dropped in numbers at the turn of the 20th century was possible social influence brought about by universal education and the industrial revolution.
These two factors would have forced lefties into the spotlight as they learned to write in the classroom or clumsily used machines built for right-handers.
"That would have exacerbated the stigma that any visible minority can experience, and the result could have been that left-handers found it more difficult to find marriage partners, marrying later, and hence having fewer children so that fewer of the relevant genes went into the gene pool," McManus told LiveScience. "And we do have evidence that around the turn of the 20th century left-handers had fewer children than right-handers."
