Fact or Fiction?: The Tongue Is the Strongest Muscle in the Body:

https://www.scientificamerican.com/article/fact-or-fiction-the-tongue-is-the-strongest-muscle-in-the-body/

It can bend, it can twist, it can suck, it can cup. The tongue is an essential, often playful part of human anatomy. Many of us grew up believing the assertion that the tongue is the strongest muscle in the body. But is it really?

The short answer is no. But the explanation is not as straightforward as you'd think.

Do Left Handed People Die Younger Than Right Handed People?

False

Three myths about elephants you probably believed, and three amazing facts you'll be glad to know:

https://www.independent.co.uk/voices/comment/three-myths-about-elephants-you-probably-believed-and-three-amazing-facts-you-ll-be-glad-to-know-8990796.html

Myth. It is true that adult elephants can't jump. But there are other mammals that can't either, like sloths, hippos and rhinos. Although, unlike elephants, hippos and rhinos can have all four feet off the ground at the same time when they run.

Snails are animals. Can they jump?

Myth: Polar bears are "left pawed":

https://polarbearsinternational.org/polar-bears/myth-busters/

There is no evidence to support the notion that all great white bears are left pawed. Scientists observing the animals haven't noticed a preference. In fact, polar bears seem to use their right and left paws equally.
