Glad to read you're relatively ok. Thank God!
Many, many, years ago, when I was a fairly new rider, I had a slow speed incident, lucky. I was wearing a helmet, leather jacket and gloves for protection. Gear held up perfectly. Jeans and two week old tennies, not so well. To this day, I have a nickel size scar above my right knee as a reminder of that day. Ever since, I wear full gear.
Additionally, when I first started tracking and racing mini moto's, I had a lot of learning experiences and still have my leathers. All the tarmac scuffs are a great reminder of what my body would look like, had I not worn any protection. I would be all but a walking scar tissue.
WEAR YOUR GEAR!
