The only problem is that when I graduated from medical school, I didn't get one of those little doohickeys that your mechanic has to plug into your car and find out exactly what's wrong with it, because the textbook of medicine is not closed.
El único problema es que, cuando me gradué de la facultad de medicina, no obtuve uno de esos aparatos que el mecánico enchufa en el auto para saber exactamente cuál es el problema porque el manual de medicina no está cerrado.
