Keep your safety gear up to date! If it's old or not functioning, fitting properly it can't do it's job and does you no good!
Several Christmas' back my son and a really good friend were in a sand car accident, the harnesses were so old that the driver's frayed apart on impact from years of sitting in the sun. Had I known or looked closer I would have never let my son in that car. Thankfully my son's harness held together and he ONLY shattered his ankle and received a contusion to his head.The driver survived, but his head hit the frame and he will never be the same.
I just got a new helmet myself, I was way over due, I believe you are supposed to replace every three years.
