I came off my bike yesterday. As I came off, my face hit the ground. Fortunately, I had a full face helmet on, so there's not even a nick on my face. My jacket was at the cleaners, so I got road rash on my arms. I wore proper motorcycle gloves, so my hands are fine. Parts that were properly protected are good as new. Parts that made contact now hurt like a mofo. Fortunately, nothing was broken. Had I worn my jacket, I wouldn't have had a single scratch on me.
Wear your gear, folks.
