How do you keep your valuables safe, no matter where you go or what you do?

We at the Clever Travel Companion love to travel! We have been to many parts of the world backpacking, going by train, bus, car and even on foot. We have been to Asia, riding the Tran Siberian train from Moscow to Beijing, driving through Mexico and across the US, inter railing in Europe, gone by bus from London to Cape Town, South Africa, worked in hotels in France and studied in Spain, just to mention a few of our trips. Most of the time we have felt and been perfectly safe. Most people, no matter where you go are friendly and helpful and wish you no harm.
