Eh it's all just Lies and Statistics. It's like how 'non drinkers' die earlier than those who lightly drink. But no one who reports it writes the next sentence to explain that, non drinkers include people who don't drink to manage chronic health conditions and thus skew things with their ill health making it seem like alcohol is required to be healthy.
I suspect in the future death by choice, in a palliative setting may go up. Though with the current waves of deregulation, maybe we're headed for more industrial accidents.
But as for the article. Places that are high up, are cold and isolated and people are social beings.
