Why can’t we stop thinking?
Try to stop thinking for five seconds.
Ready?
…steady…
……GO!
Okay, now you’re just reading this and not-stopping-your-thoughts!!
So why can’t we stop thinking? Well, this is the handiwork of our old friend, evolution.
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."
