#15. Hurling

Hurling is one of the strangest sports that the Irish have invented. Surely, the rules of this sport were invented by a lot of Irish drunks in a local pub. It’s a mix of rugby with grass hockey, all that, without the protection of a proper safety equipment. Excellent! If you like extreme sports and you wanted to know what it feels like to receive a concussion, then go ahead and join the hurling team of your school.
