My sister PJ was left-handed, and all the rest of her five siblings are right-handed. While gathered with family, we discussed the statistics of handedness, and of course I opened my laptop to find out what the internet had to say about it. I always suspected that when I was little, I might have been forced to write with my right hand. The reason I wondered about it is that there are many things I do with my left hand, like deal cards, where a "normal" right-handed person wouldn't.
Nobody is around any more who could answer that question, but in my research I was really surprised to find out there are actually four different types of handedness: left, right, mixed, and ambidexterity. You can read what Wikipedia has to say about it here. Interestingly, I discovered that it's probable that I am naturally mixed-handed, as about a third of people are. Around ten percent are left-handed, and true ambidexterity is exceedingly rare, although it can be learned, and all the rest are right-handed.
Fascinating! In our six siblings, we had one lefty, four right-handed, and one mixed. I also learned that there are several different ways to determine your natural laterality. (Isn't that a great word?) One is to clasp your hands together. About 60% of people naturally put their left thumb on top (I put my right one). Or, even more interesting, how about folding your arms across your chest? More than 60% of people, no matter their handedness, fold their left wrist on top (so do I). I found all this information on this site about handedness statistics.
When we were at my brother's house discussing all this, he said, "I smell a blog post coming." And he was right; here it is! I'm on my way to the eye doctor's office for my annual visit in a few minutes, and I'll have to leave it here. But coming up soon: do you know how to determine which is your dominant eye?
