Input: Text: this happened a few years back when i was outside, just chilling. i decided that it was nice weather for a quick run, so i walked to the steps in front of my house to get ready. for shits and giggles, i placed my foot on the lowest step to boost myself forward, similar to how a sprinter places his or her feet on a block.

i took a deep breath, pushed my foot against the step, and lunged forward -- onto the fucking ground. i wasn't even aware that i was falling until it was too late. you would think that i would be okay because i'd have something to cushion my fall, such as grass, but no! i fell right onto the concrete sidewalk headlong. as my head crashed onto the concrete, i must have been knocked unconscious for a few seconds. when i regained my conciousness, i got up and examined myself, and sure enough, i had multiple injuries.

both of my knees were scrapped, with bright red blood oozing out. i felt my sprained ankle throbbing with sharp pain. i must have scratched the skin near my eyebrow, because i felt blood trickling down my bruised forehead. worst of all, my right arm hurt like hell; i clutched my broken arm in agony and limped into the house.

i had to go to the hospital, and i was given an x-ray of my arm, and my wounds were bandaged up. for the following days, i suffered through many ordeals (including excruciating pain). i had to adjust to writing with my left hand throughout the week. i had to lie in bed most of the time because of my sprained ankle.

needless to say, i never tried anything stupid again while running. but hey, at least i learned to write with my left hand.
