Chau Smith was always an avid runner, and, in 2017, she decided that for her 70th birthday, she would complete seven marathons in one week across all of the continents. Traveling made it challenging—for example, Smith made the race in Egypt just minutes before the start because her plane to Cairo was delayed. But despite the obstacles, she completed her goal.

The first mobile device to be called an "iPhone" was made by Cisco, not Apple. It allowed the user to use the voice functions of Skype without a computer. Apple announced its own product just 22 days later, and Cisco sued for trademark infringement. The lawsuit was ultimately settled out of court and both companies were allowed to keep using the name. However, you've probably never heard of the Cisco iPhone.

Entomologists have estimated that there are at least one million trillion insects and only one percent of that number is ants, according to the BBC. And if you took all those ants (about ten thousand trillion) and put them on one side of a giant scale, you could almost put all of the people in the world onto the other and balance things out. Unfortunately, as humans have become heavier, this probably wouldn't hold up today—but it once did. Francis Ratnieks, professor of Apiculture at the University of Sussex, told the BBC this might have held true around 2,000 years ago.
