The Blue Blood Myth

MYTH: THE BLOOD LEAVING YOUR HEART IS BLUE. FACT: IT'S ACTUALLY DARKER ReD. The myth that deoxygenated blood is blue comes from the fact that through Caucasian skin, veins often look blue. While it's true that those blue vessels you're seeing carry blood without oxygen, the blood itself is actually not blue. The veins aren't blue, either.

Sitting Close to the TV

MYTH: SITTING CLOSE TO THE TV HURTS YOUR eyes! FACT: THERE'S no science TO BACK THAT UP. If there is a correlation between bad eyesight and sitting too close to the TV set, it's the other way around: People who sit close to the set do so because they already have poor vision. Staring at a screen for long periods of time can make your eyes tired and irritated, but that's because when you focus super hard, you forget to blink.

MYTH: A STRONG immune SYSTEM FIGHTS COLDS. FACT: A COLD IS YOUR immune SYSTEM. Despite the rhetoric of the immunity-booster industry, a strong immune system won't keep you from getting a cold.

In fact, the cold virus is actually mostly harmless, except for the fact that it causes your immune system to go bananas. CRACKED.COM https://www.eurekalert.org/pub_releases/2008-10/pg-fcg102408.php
