Hmmm — isn’t it possible that too much awareness of our pending apocalyptic peril at the mercy of the Yellowstone Caldera is what’s arresting your slumbers in the first place?
If only my late night existential crises were based on realistic apocalyptic peril, rather than some kind of unknown that's impossible to put into words. At least then, there's some kind of science and "natural rules" to limit the exposure.
