Imagine if you were talking to a surgeon, and you say, "Listen, buddy. I've had a heart for, like, 40 years now. I think I know a thing or two about aortic valve replacements. I think my opinion is just as valid as yours."
Imaginen que conversan con un cirujano y le dicen: "Ey, amigo, llevo cerca de 40 años con este corazón, creo que entiendo algo sobre la sustitución de la válvula aórtica; mi opinión es tan válida como la tuya".
