Interesting feedback here. I don't think we can come out with any hard stats simply because, as CollinMum says, we don't have the parameters (total number of respondents vs total pool of forum members, not to mention that some may not have seen the thread at all). This is just for anecdotal sharing, and I must say there are quite a few interesting thoughts here.

Evidently, some ambidextrous kids have no difficulty wiring to both sides of the brain at all, contrary to what I thought. And I've always suspected my son was dyslexic although he's been cleared. But he still reverses letters, numbers, ideas even. Left to right, right to left, is the same to him. When he's alert, its alright. But when he's tired, he switches back into default, which is reversals.

Interesting, all this!
