"The thought first occurred to me in Battlefield 2 as I felt the impact of a long-range headshot while sliding down a zip line in the middle of a fire fight. It may be the most efficient way to travel in a playground, but in the battlefield it leaves you unable to return fire for the duration of the slide. You're effectively hung out in the open like a slab of raw meat before a pack of hungry dogs. Making it across unscathed would have been more shocking than what befell me. So why'd I keep doing it?
As I completed my tenth zip line run, up popped a little icon accompanied by a military fanfare, and suddenly I knew the answer: because I was weak."
