Understand the risk of terrorism in a cold, logical, statistical way. If you want to take that risk, travel in a way that minimizes that tiny threat. Let me explain. Consider the emotional style in which terrorism is covered and how expertly terrorists are milking that, even providing TV news broadcasts with video footage. It's quaint to think that our news media is interested in anything other than ratings and selling advertising.
Terrorism sells ads big time.
If I'm in Europe and there's a boat hijacked or a train wreck in Italy, I always call to let my mother know I survived. Assure those who'll worry about you that you'll call home every few days. Talking to people about local problems is fine. Dodging bullets isn't. English newspapers and broadcasts are available in most of the world.
