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.
This usually includes a helmet, shoulder pads/chest protector, elbow pads, mouth guard, protective gloves, heavily padded shorts, a 'jock' athletic protector, shin pads and a neck guard. Goaltenders wear masks and much bulkier, specialized equipment designed to protect them from many direct hits from the puck. The hockey skate is usually made of a thick layer of leather or nylon to protect the feet and lower legs of the player from injury. Its blade is rounded on both ends to allow for easy maneuvering.
