I know they were around by the late 70s when I started school, because I remember thinking they were special because hardly anyone got to use them...

Hand preference decided at 10 weeks
LONDON (Reuters) - Whether a person will be right-handed or left-handed could be decided early in the womb when the foetus is about 10 weeks old.
Scientists who studied ultrasound scans of 1,000 foetuses and followed the progress of some of them after birth, found that if a foetus preferred to suck its right thumb more than its left at 10 to 12 weeks old the child tended to be right-handed...
...The findings, by Peter Hepper and researchers at Queen's University in Belfast, Northern Ireland challenge current thinking that hand preference does not develop until a child is 3 or 4 years old...
But, I wipe mine with my right!ScabbyDog said:What I did find very awkward was whilst in Indonesia I had to force myself to eat using my right hand, its seen as very rude to eat with your left hand (apparently they traditionally use it to wipe their backside).
Me too, and I haven't even got the excuse of being left handed. When navigating from the car passenger seat I have to say to Hubcap "your direction" for right and "my direction" for left, as it needs to be done quickly and I so often get L and R mixed up if rushed.Min Bannister said:And of course I am useless with directions. I usually just have to point because if I try and guess whether a direction is left or right I inevitably get it wrong.
Kind of daft that, there are only two choices. I am capable of learning vast amounts but I can't seem to learn this.

I use single items of cutlery in the left hand. Spoon, fork, splayd (or splade or splayde - kind of like a spork), and chopsticks (which counts as a single item). I'm also much more comfortable using a soup spoon over a desert spoon. (The circular one, not the sort of trapezoidal/elliptical one.)

Summary:
It is not the brain that determines if people are right or left-handed, but the spinal cord, new research indicates. The biopsychologists have demonstrated that gene activity in the spinal cord is asymmetrical already in the womb.
A preference for the left or the right hand might be traced back to that asymmetry. "These results fundamentally change our understanding of the cause of hemispheric asymmetries," conclude the authors. The team report about their study in the journal eLife.
