Not really injury, most like hurting myself.
I was in Rio about a month ago having blast in Rock in Rio. It was the last days of the shows and because axl rose was late or something guns n roses came on very late.
The show ended at about 5 AM. Being unfamiliar to Rio and hadn't a clue where the buses were, i climbed like a taxi for many people. So in the taxi i had no room to sit, so i sat on the edge of some seat with me facing the sliding door at the side of the van. I was so tired i fell asleep and slammed my head again a handle bar, instantly waking me up. I felt so dumb it happened to me in a van filled with people, i of course had to fall asleep again and slam my head once more...and once more.
Never have i been so tired where i couldn't even stop myself from falling asleep to keep my poor forehead alive.
