Would it more likely mean that you are more skillful when your feet are in contact with the ground that when balancing a bike. I would bet a fair sum that if you gave anyone the choice of walking across ice or riding they would choose to walk because it is safer, not rocket science is it?[/quote
I am sure that I am more skillful at correcting my balance when on two feet rather than two wheels. I am not sure what point you are trying to make. Ice only factored into yesterday's tumble. As to it not being rocket science. .. I believe that that's Astro physics - which I don't profess to have any knowledge in whatsoever.
