The problem is, you buy a basic medication, you buy an electrical appliance, it comes with warnings about how it can kill you. We're used to seeing 'may cause death' on things that are tested again and again before being released to the market. So when we see it, and the risk is real, how are we meant to know the difference? Especially when the man selling it to us tells us "it's unsinkable, I'm going along on this dive myself?" We assume that behind that man, unseen, are a whole lot of folks who have done their due diligence to meet some standard, to ensure safety, because that's what happens in every other aspect of our lives.
