Short excerpt from a YouTube talk arguing that social isolation is one of the largest negative factors on human lifespan outside of terminal illness or trauma. Speaker cites ‘‘blue zones’’ and longevity research and makes the strong claim that prolonged isolation can halve life expectancy, framing isolation as a comorbidity comparable to major health conditions.

I talk about this all the time, about how in blue zones and longevity research, isolation was the single biggest impact other than, you know, terminal illness or trauma. Right. But isolation for human beings as a comorbidity, which is how we put things into the model, had one of the greatest impacts on lifespan. So if you wanted to cut somebody's life expectancy in half at any age, you would put them in isolation. You know, broken heart syndrome, we have these terms, but they're very real issues. We can be isolated in plain sight because we've isolated, isolated ourselves.
