I am a student. I live in a hostel. Today early in the morning I feel hungry so I wake up and went out of the hostel to a shop which remains open all the time to eat bread and biscuits. I didn't wash my face and mouth. I got up from the bed and I went straight to the shop. As I didn't wash my face so the sleepy feeling didn't go away, so in the road I was moving like a sleepy person ,Like I lost my balance. Suddenly a bike hit me from back and I fell down on the concrete road. I got hurt in my back and my head. However I have no cut or bleeding. I just have a little inflammation in my head. Will anything happen to me? Will my Brain get damaged? Is my Brain safe? Will I lose my memory power?
