That's messed up, no one should be doing anything that risky without taking proper health and safety precautions. That show ought to be cancalled. Celebrities shouldn't have to risk their lives for our entertainment.
That's terrifying! I've gone zip-lining before, and you really DO need that protective gear. The speed you go through is incredibly fast and it's too risky without gear to protect from that. RIP to the idol that died doing this.
