As someone who spent 2 tours in Iraq with the 101st Airborne, I think I'm qualified to make the statement I did. The world is full of scary things, sure. But if you let them limit your experiences then what's the point of living in the first place?
I'm happy to go to Iraq.....just so long as I can go with a few thousand friends armed with M-4s.
Caution and fear are two different things. Saving the trip to Mexico for another time when they aren't in the middle of a all-out war on drugs doesn't mean one isn't "living life."
