Problems with my father

Let me tell you a bit about my father. If you are a guitarist, and have ever used an Echo-Flanger (Or Poly-Chorus), BassBalls, or Small Clone, my father designed it for Electro-Harmonix. I tell you this because he was sick for the past month or so. His armpits were swollen with lymph. Now he's sitting in NYU Medical Center getting checked up. Right now, his status is up in the air. I'm afraid he will die, maybe of cancer or something. My father knew so much tech, that I don't know where I would turn if he were to leave me.
