Electric blankets are safe when used and stored properly, but children, pregnant people, and those with diabetes or circulation issues should avoid using them.

Fact

People didn’t think the Earth was flat in ancient times.

Despite what popular fiction or conspiracy theories say, the ancients knew the Earth was round. They noticed this from observations on how ships slowly disappeared below the horizon as they sailed into the distance. The mathematician Eratosthenes even calculated Earth’s circumference with an error of only 15% during the 1st century BC.

Scholars preserved this knowledge even after the Fall of the Roman Empire, and while it took Magellan’s expedition to prove it, academics even at the time already knew the Earth was round. Definitely one of the Earth facts to remember.
