All Cack Handed

Left-handed people have been urged to celebrate their physiology for International Left-Handers' Day.  The Left-Handers Club is urging Barack Obama, David Cameron and others to create left-handed zones in their homes and workplaces and organise left handed games.  It said:

"Left-handers everywhere can celebrate their sinistrality and increase public awareness of the advantages and disadvantages."

International Left-Handers Day was started by a US group in 1976 and is marked with informal events around the world.  Participants can download posters, songs and quizzes aimed at celebration their unique abilities.

In an odd coincidence I know three people all born on the same day (13th March; my father, Sue and Bryan) and they are all lefties- what are the odds on that?

Around 13% of the world's population is thought to be left handed, although there are wide geographical variations.  The proportion is much lower in Asia, which has been linked to forms of cultural discrimination.
