YOUNGSTOWN, Ohio (WYTV) – In our world of search engines and social media, misinformation is everywhere. Here are some examples of some accepted beliefs that just aren’t true!

Myth: Bats are blind and use only echo location to get around

Truth: All bat species have eyes and are capable of sight. About 70 percent of bat species use echo-location to navigate. Some can’t echo-locate and have excellent night vision


Myth:
The daddy long legs spider is the most venomous spider in the world but can’t bite because its legs are too long.

Truth: They are NOT the most venomous spider. They can bite humans, but the tiny amount of venom they carry causes only a mild burning sensation for a few seconds.
Myth: Human blood in veins is not actually blue.

Truth: Blood is always red due to hemoglobin. Veins look blue because of the way light interacts with our skin. Deoxygenated blood, or blood inside the body, has a deep red color. When you get a cut and bleed, the blood comes in contact with the oxygen and it turns a brighter red color.
Myth: Eight glasses of water a day are needed to maintain health.

Truth: The amount of water needed varies by person, their weight, activity level, clothing and environment
Myth: Swallowed chewing gum takes seven years to digest.

Truth: Chewing gum is mostly indigestible and passes through the digestive system at the same rate as most other things.
Myth: The Twinkie has an infinite shelf life.

Truth: It has a shelf life of approximately 45 days (25 in its original formulation) – far shorter than some people believe
Myth: Matadors use red capes because bulls are enraged by the color red

Truth: Red doesn’t stand out as a bright color to them. Bulls charge because they feel threatened.
Myth: Goldfish have a memory span of just a few seconds.

Truth: They actually can remember for months.
