A duo of 81-year-old women are on the adventure of a lifetime: Seeing the world in 80 days

Sandy Hazelip and Ellie Hamby are on a mission to see all seven continents, nine Wonders of the World and visit 18 countries in just over two and a half months.

So far, they're making good progress: Hamby and Hazelip have set foot in Antarctica, and on Mar. 4, they saw the world from a plane flying over Mount Everest.
