Without a doubt, Niagara Falls is one of the most impressive waterfalls in the world. The sheer amount of water surging around you is simply sublime. In fact, when Austrian composer Gustave Mahler first encountered the falls, he is said to have exclaimed, “At last, fortissimo!”

Would you buy someone else’s long-expired passport? What if the passport showed that, many years ago, the person lived in the same place where you live now?
For Nuno Fonseca, a Portuguese medical student studying in Paris, the pull of the mystery represented by a 60-year-old passport he found at a flea market was too strong to resist. The long-lost passport was covered in stamps from Europe and the Middle East, and its original owner had once lived in the exact same student housing complex as Mr. Fonseca.

A friendly reminder, folks – just because your passport hasn’t expired yet, that doesn’t necessarily mean you can use it for travel.
