Because the Earth is a three-dimensional sphere and not merely a two-dimensional flat, East-West surface.

Crohn's disease and kidney failure. Last year I went to the ER on November 14th because I was extremely sick, and thought I had appendicitis. I was extremely thirsty, nauseous, had extreme chills, bloody diarrhea, and bad stomach pains. Turns out I had kidney failure with a creatinine level of 5, almost to the point of needing emergency dialysis. I've had two kidney biopsies, and they showed I had interstitial nephritis. My doctors think it was either caused by proton pump inhibitors (omeprazole) or a rare manifestation of my crohn's disease. I was referred to the mayo clinic to treat both the crohn's disease and the kidney failure.
