jauntie, I do quite understand where you're coming from.
The answer you gave was brilliant as it put a scientific reasoning behind such things.
My post really was asking others if they noticed the same sort of things that I did, once it'd been commented about my using different hands for different actions/jobs etc.
When you pick up something, throw something, pull something, why do you use one hand rather than another, irrespective of your natural handing? That I think is the answer your post was looking to clarify.
Do you agree?

Torque is good!
