A horse named charley

Although we may fight for it, in the end we just can't stop people from naming their horses "Charlie". But maybe we can help them with an involuntary contraction or spasm causing a muscle cramp, sometimes called a "charley horse". Usually they occur due to an overused or injured muscle, but can also be caused by lack of minerals such as potassium (1). So, before and after exercise, eat your bananas.
