Once every 600,000 years, Yellowstone erupts. Once every 10 million years a meteor about a mile across hits Earth. I think that in the foreseeable future we are much more menaced by government overreach than being buried in volcanic ash or incineration.
And once every 2 years we have a meaningless election where we go to the polls to send people to Washington to rob us of our life, liberty and pursuit of happiness.
