>Hair and fingernails continue to grow after death
Nope. What is actually happening is the skin on the tips your fingers and hair follicles is receding, creating the illusion of growing hair and nails.

>Christopher Colombus was the first European to discover Earth.
Nope. Lief Erikson arrived in Newfoundland, Canada centuries before.

>The toilet was invented by a man named Thomas Crapper
Nope. While the man was one of the several pioneers of the flush toilet, he did not invent it.

>The word "crap" was derived from Thomas Crapper's surname
Nope. It was already an established word long before Thomas Crapper's birth. The word ultimately derives from the Latin "crappa" meaning chaff.

>Water contains more oxygen than air
Nope. Water contains two oxygen molecules and one hydrogen molecule, meaning it is 2/3 oxygen. Air on the other hand, with the exception of trace amounts of other gasses such as smoke (gaseous carbon), is 100% oxygen. If water really did have more oxygen than atmosphere, then humans would be able to breathe underwater.

Obviously they can't. You would have to breathe in 1.5 times as much water as you breathe in air to be able to survive off water. You would initially survive, but breathing in this much water would cause immense strain on your heart and cause you to die.

>Only 10% of the brain is being used by the average person.
Nope. While it is true that a small minority of neurons in the brain are actively firing at any one time, the inactive neurons are important too.
