Knuckle Cracking

Question:

If you sit too close to a TV, you will ruin your eyes.

Answer:

False

No studies have shown a link between watching television and damaged vision. It is true however that sitting too close to a TV or watching in a dark room can cause eye fatigue, but the warning of permanent damage does not appear to be justified based on the studies. It is probably a good idea to sit at least 4 or 5 feet from a TV and keep a dim light on in the room.

Answer:

Sink to the bottom of the ocean

A shark will sink to the bottom of the ocean if it ever stops swimming. Sharks lack the pocket that helps keep most fish buoyant. Sharks have large, oil-filled livers that serve a similar purpose, but with the help of their liver they’re still denser than the water. This is why they must swim continuously to stay afloat.
