We came across an interesting snippet of information in our research today; apparently, if you're left-handed you're more likely to suffer from periodic limb movement disorder - a sleep disorder that's closely related to restless leg syndrome.
Unfortunately, the study doesn't explain why those who are left-handed seem to be more likely to suffer from periodic limb movement disorder (we'd hazard a guess that it's something to do with the way our brains are wired) but the results were stark; 94% of left-handed patients in the study had bilateral limb movements compared to 69% of right-handed patients.
Not only do left-handed people get their own stores, it looks like they also get their own sleep disorders, too.
