I used to ride without a helmet, till I learned the hard way. I used to ride my horse and several other horses I thought were safe, without a helmet. Well, the day I learned my lesson, I was fortunate enough to have been wearing my helmet. I had a jumping lesson on my horse in the morning, and I always wore a helmet when jumping. I had three other horses to ride in the afternoon, and I didn't bother to take my helmet off, thankfully. One of the horses, a big bay gelding, was on my safe list. Thankfully, I got on him with my helmet still of from having had the jumping lesson earlier. Every thing was going fine. We were cantering around the arena when he suddenly collapsed. He didn't trip or stumble. He literally just collapsed. My head slammed into the wall and my left leg was pinned completely underneath the horse. The horse was a pretty gentle guy, and he rolled off of me onto his stomach, waited for me to shimmy out of his way, and then got up. Most any other horse would have gotten up on top of me. My helmet was dented and had to be replaced, and my left knee was absolutely shot to hell. I have arthritis in my knee now because of that incident. I would have had a severe concussion and probably brain damage if I hadn't had my helmet on. It was a heck of a lesson to learn, but since that day forward, I always ride with a helmet. You just never know.
Strength is not defined by physical ability. It is determined by your actions and the compassion of your soul.
