Fun Fact: Around the World in 80 Hours, Not 80 Days
Jules Verne’s classic novel imagined a daring trip around the world in 80 days. Today, if you pieced together optimal commercial flights, the flying time alone to circle the globe is only about 40 hours, so the whole trip can fit within 80 hours. So when you set your 80 hour timer, imagine yourself traveling around the world: mentally, physically, or creatively. It’s a powerful window for exploration and growth, even if you never leave your desk.
Radon-222, a natural radioactive gas, has a half-life of about 3.8 days. This 80 hour timer ends 11 hours, 40 minutes and 48 seconds earlier.
