Ten More Fascinating Body Facts

From the age of thirty, humans gradually begin to shrink in size.
Most people lose fifty per cent of their taste buds by the time they reach age sixty.
Your body contains enough iron to make a spike strong enough to hold your weight.
The amount of carbon in the human body is enough to fill about 9,000 'lead' pencils.
One square inch of human skin contains 625 sweat glands.
The surface area of a human lung is equal to that of a tennis court.
Give a tennis ball a hard squeeze and you use about the same amount of force your heart uses to pump blood around your body.
When you blush, your stomach lining also reddens.
The human body has less muscles in it than a caterpillar.
Your eyes blink enough times in a lifetime to see blackness for over a year.

Diamonds are Formed from Coal Myth Debunked

According to evolutionists and geologists, diamonds were formed about 1 to 3 billion years ago, much earlier than any known record of Earth’s first land plants. Coal is formed from the dead remains of vegetation like trees and other plants. The formation of coal takes millions of years and can be traced back 300 to 400 million years, but not a billion years.

Coal is an amorphous form of carbon and at the most can change its chemical composition and transform into its nearly purest form which is Graphite, but not diamond. The conversion of coal into diamond is almost impossible due to its impurities and the fact that coal is rarely found at depths greater than two miles which is not conducive to the formation of diamonds.

Natural diamonds require depths of 87 to 120 miles in the Earth’s mantle, very high temperatures, and resulting pressure that exists at those depths to form. Unlike other gems which are formed by a combination of elements, diamonds are made up of one single element, Carbon. Carbon-containing minerals present in the Earth at those depths, crystallize to form diamonds, because of the immense pressure together with the heat from molten magma.

The diamond crystals, along with other minerals are transported to the earth's surface during deep-source volcanic eruptions in the magma. This is quite a rare occurrence as diamonds are formed at depths usually 3 to 4 times deeper than normal volcanoes originate.

Diamonds color is influenced by impurities and can be blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange, red, and grades of those colors. Red diamonds are the rarest and most exotic diamonds. They are also the most expensive. Here are examples of a red and orange diamond.

When this magma cools, it forms igneous rocks known as kimberlites and lamproites, used as an indicator by geologists that diamonds may be found in the area. The Kimberlites form narrow pipe shaped fissures which are also referred to as diamond pipes. Many of the pipes are also rich sources of garnets. The most prominent kimberlites are located in South and Central Africa, which contribute almost half of the natural diamonds mined in the World. Over 500 kimberlite deposits have also been found in Northern Canada.

Africa, Russia, Australia, and Canada are the largest diamond producing countries. BTW - Diamonds are not in short supply and are a terrible investment because there is no aftermarket.
