We’ve all done it. You throw your clothes in a bag and head to the airport. Sixteen hours later, you’re in a country where the customs, dress, language and food are very different from home. As you leave the airport, you stop at an ATM, and within seconds have enough local currency for a taxi and a few meals. All you needed was an ATM card and some money in the bank.
In fact, your trip is going really well until you slip on some ice and fall down a flight of stairs. As you tumble to the bottom and see your femur bone break through the skin, you wonder whether you will be awake to tell the hospital about your allergy to local anesthetics and your heart disease, which has left you with an abnormal heart rhythm.
