We can ignore the 1 in 20 as it’s based on only 4 deaths. But faced with a 1 in 60 death risk? Perhaps they tell themselves it’s a one-off risk so is acceptable for the experience. But it’s nearly twice the lifetime risk of dying in a car accident, and to me they’re unacceptably bleak odds, especially since for most people it’s basically an expensive, exhausting plod in dicey conditions. Nor would I feel comfortable marketing it to frustrated middle-aged businesspeople.
