A friend asked me to interlink my fingers and rest them on my lap. Supposedly, the ruling thumb (the one that is on top) will indicate which part of my brain governs my actions (ie. left ruling thumb indicates left-brainer and vice versa). However, since the left brain controls the right side of the body and vice versa, does a left ruling thumb mean I'm a right-brainer instead? Or is it just hogwash anyway? lol.
