Worldwide Caution
Before retiring (work!) and continue the practice....if the state department cautioned or warned against a particular country we would not allow our people to go there.
General cautions as above are more difficult to deal with as they are so wide and general. Best approach? Do what one MUST do....exercise common sense...be aware of your surroundings....alway/always/always be aware of entrances and exits to or from where one is.
Another tip is when you check into your room in any hotel/motel, be sure you know exactly where the exits are. It only takes a minute and could save your life.
Paranoid? NO! Common sense safety awareness.....huge return on investment of time taken!
