Sorry, it seems like most of the grace have downloaded it wrong - pineal grand in brain, part of penis...etc. I meant it simple - normal human has 2 eyes, bassists are normal, too. What if some of us had 3 instead of 2 eyes, would it be easier, more effective to play the bass if You could use 3 eyes instead of 2. That's it....nothing more, just a futuristic situation.
