Part of my job requires that I spend a lot of time in the car. Which I really don't like to deal with at all. The main problem is that no matter how well I try to pay attention to everything going on around me, there's still a huge chance that I am going to get blindsided by something.
The largest concern is the presence of those giant green road signs. Usually the ones that sit under bridges. The big scary ones that get caught by the wind and flap around like crazy. They are made of steel and if falling from high enough at exactly the right moment, could rip through the roof of my car and cut me in half. Sure, death would be instant but it would be a disgusting mess.
The easiest way to prevent them from falling on my head is to grit my teeth, force my tongue into the roof of my mouth and inhale quickly. This gives what I presume to be a protective shield around my head. So even if they did fall, I would remain unharmed.
It's worked pretty well so far.
