Jack Wheeler proudly shows the passport issued in the 1960s, among all the passports he has had over the course of his life. He has brought the documents to prove that he has visited every country in the world.
“About 20 years ago, my wife asked me how many countries I had been to. It turned out I had been to 140. And she said: ‘Why not visit them all?’” explains Wheeler, an American who lives in Portugal with his wife.
