Ah sleep, so peaceful!

So, why do we sleep?

Well, first of all every animal with a brain sleeps.  A lot of really important things happen while we are off in dreamy dream land. Sleep is when the body gets a chance to repair and process things.  This allows our brain to be refreshed and our cells (throughout the body) to get repaired,  an important part of how wounds heal! 

In 1977 NASA launched Voyager 1  and 2, two probes boldly going where no spacecraft had gone before!  After 35 years of zipping through space these ultimate inanimate explorers still work and are still communicating with us!  The Voyager program has been a vital source of information used by astronomers in understanding more about our own cosmic back yard.

400 years ago lead was harnessed to wood and thus pencils were born!  Today, most pencils are made of graphite surrounded by a wooden shell.  The average pencil can draw a line for about 35 miles!  If you're not drawing 35 mile long lines you could be writing words, about 45,000 words is the average life span of a graphite pencil.

The Human Heart is pretty amazing! It's the power house of our circulatory system. One muscle with four chambers that pumps about 1900 gallons of blood every single day!  That's pretty impressive considering that this vital organ only weighs about 10 ounces.  Don't let size fool you though, the heart's work goes a long way, literally!  The average adult human circulatory system can actually reach about 60,000 miles.

Painter, inventor, scientist, and all around smart guy, Leonardo Da Vinci, once said: "The human foot is a masterpiece of engineering and a work of art."
