Usually try to refrain from commenting on people stupid enough to remove themselves from the gene pool in new and creative ways as recounted at the Darwin Awards, but sometimes you just gotta do it.
Maybe this stems from my very rational fear of heights, due to great respect for effects of gravity, so I'd avoid zorbs near cliffs.
Hmm, strapping yourself inside of 2 plastic balls and rolling down a ski slope, what could possibly go wrong with that? Video found at Earthbound Misfit's place: http://eb-misfit.blogspot.com/2013/01/blog-post.html.
[It was supposed to be a thrilling ride down a ski slope inside a giant inflatable ball that is to be one of the symbols of next year's Winter Olympics; it ended in tragedy for the two Russian men inside.
The transparent plastic ball — known as a zorb — veered off course and sailed over a rock ledge in the rugged Caucasus Mountains of southern Russia. The ball picked up speed as it flew down the steep slope, rolling and bouncing. One man was killed and the other badly injured.]
