The truth is that there is no more a link between star sign and intelligence than there is between madness and creativity. That a link has been drawn between the two is, however, under–standable. How else can we explain the outrageous creative power of a Mozart or a Beethoven without resorting to some kind of brain chemistry imbalance? If these guys were as normal as everyone else, then where is the magic? It is the sad way of the world that someone doing something extraordinary (Beethoven) has to have an extra dollop of extraordinary (bipolar disorder) to make it, well, even more extraordinary.
