Fall down

During I moved to bicycle store in the dark, I fall down on the road. Some place of the bicycle was damaged. And some point of my body had pain.
But, my bone was not broken. It may be lucky. When I fall down, the speed was near 20 km/h. If I died at the accident, it was not mystery.
The reason was that I could't find the small stage on the road. I had to be care in dark.
