I live on the sunny, tropical island of Okinawa, Japan. During the summer the temperatures stay in the upper 80s to lower 90s and with the humidity at 70 - 80% it is damn hot. I see many bike riders do not wear the appropriate safety gear due to the heat. The other day I was in my van with my wife at a stop light and there were about 5 cars in front of me. There were cars parked on the side of the road. A Japanese guy on a CB400 passed between the cars parked on the side of the road and the cars waiting for the light. You guessed it. A lady parked on the side of the road about 2 cars ahead of me opened her door just as the CB400 was passing by. The CB400 swerved to the right and missed a major head-on collision with the door. However, his left foot caught the bottom corner of the car door. I saw him stop, let his bike drop to the ground, and he crawled over to the sidewalk. My wife and I jumped out of my van and went to help him. When we got to him he was laying on his stomache writhing in pain. We took a look at his foot and the skin on the entire top part of his foot was tore back. We could see the bones, tendons, and ligaments inside his foot. Apparently he cut a large vein and his foot was pouring blood out (not a drip or an ooze, pouring out). My wife used to be a nurse and immediately treated his wound while I applied a tourniquet to his leg. After a few minutes the bleeding slowed down considerably. The ambulance arrived about 10 minutes later just as the guy was going into shock. The ambulance took him away and I don't know what happened to him. He was wearing shorts, a tanktop shirt, sandals, and a helmet. Ever since that day I have worn steel-toed boots while riding. Please, please, please wear the appropriate safety gear everytime you get on your bike. Can you imagine bleeding to death out of your foot, what a way to go (I don't know if the rider in question died, but it is possible). Don't let the hot weather stop you from using your safety gear. It is better to be a little uncomfortable than to chance getting seriously hurt or killed because you weren't wearing your safety gear.
