I’d be surprised if you haven’t heard of Wim Hof – if you’re like me, someone probably mentions him every time you jump in an icy alpine stream. The man is an extreme-endurance athlete, who’s put himself through some bloody tough yakka – from summitting Mt Kilimanjaro in shorts to running a half marathon, barefoot, above the Arctic Circle – thanks to his self-developed breathing and cold exposure method that’s helping prove people are tougher than they think.    The Wim Hof Method has taken the world by icy storm and you probably know plenty of people who exclusively take showers now because of it.  Well, the man is coming Down Under to host his masterclass, including guided ice baths, to the attendees at Human Kind Festival, a not-for-profit festival held at Sydney’s Luna Park.
