I would survive the apocalypse, by making my way to the predicted epicentre of our imminent catastrophe as soon as the signs became apparent. Secure in the knowledge that our distant descendants will have one day invented time travel, and been irresistibly drawn back from the far future to observe such a seminal event in their ancestor's history. Scanning the crowds for the person wearing strangely shiny fabric and unusual headgear, I would neutralise him with a non-lethal throw, and force him to take me back to his time capsule. Using my singular powers of persuasion and the offer of my services in a modestly paid position as a historical exhibit, I would convince him to take me to this happy future, departing mere seconds before the end of the world as we know it/knew it. Thus bypassing the next ten thousands years of environmental and economic ruin.
