Fun Fact #1
About 85% of people breathe out of only one nostril at a time. Generally, people switch the nostril they breathe out of every four hours. This can vary depending on your body position and nasal congestion, though.
Fun Fact #2
The diameter of Pluto is roughly 2,390 kilometres across, which, for comparison, is about 70% the diameter of the Moon and 18% of the Earth's diameter. This makes Pluto roughly the same size as Russia.
