Yes, yes, we love videos of dudes rollerskating down volcanoes. Snowboarding off cliffs. Sure, you can climb up the side of an apartment block and run across the roof like a lemur. That’s swell. You can sit on an airbag wearing a hockey helmet and undershorts as good as the next guy, it’s true. We adore it all, every last loose tooth and road rash. But compared to the military, it’s all conversation.
