#2) Most places are as safe (or safer) than home.....In over 365 days on the road, staying mostly in dormitory-style hostels and traveling through several countries considered 'high-risk,' the only incident I had was an iPhone stolen out of my pocket on the metro in Medellin, Colombia. I didn't even notice and deserved it for waiving the damn thing around in the wrong part of town. Most people think that in a place like Colombia you'll still get kidnapped or knocked off by a motorcycle assassin, but that's not true.
