Are you the athlete type or the artsy type?

We all know that there's the athlete types and there's the artsy types. But should we rather be a mix of both?

Consider this quotation from the book A History of Western Music by Burkholder, Grout and Palisca. 

"Plato and Aristotle both argued that education should stress gymnastics to discipline the body and music to discipline the mind. In his Republic, Plato insisted that the two must be balanced, because too much music made one weak and irritable while too much gymnastics made one uncivilized, violent and ignorant."

 
So, fellow performers, on to the gym!
