SO im wondering about synthetic oil in my 2012 corolla and how many miles is safe to go over without changing it. You could change 100% synthetic oil at 6-9k miles and not have a problem (synthetic blends and regular dino oil at less mileage). This information is all over the Internet...
Usually the field hockey goalkeepers must wear extensive additional protective equipment including chest guards, padded shorts, heavily padded hand protectors, groin protectors, neck guards, arm guards, and like all players, they must carry a stick.
Field hockey presents numerous opportunities for injuries due to the fast paced, repetitive actions of the sport and the use of a long, hard stick and equally hard ball. A high proportion of these injuries can be prevented by ensuring the correct protective equipment is worn.
