In case you missed this last time I posted it.
Sitting in front of your computer rotate your right foot clockwise. Keep rotating it and at the same time draw a number six in the air with your right hand and see what happens.
Sachs it may be because you are left handed. Both actions shpuld be done with the right hand and foot and it impossible to make them go in opposite circles. However, there are a few people who seem to be able to do it.
I think the people who do manage to do this are drawing the six from the bottom upwards ie in a clockwise curve. There is no problem then only if they go in different directions.
