The human brain is the world’s most powerful computer. When it comes to sheer computational strength, today’s state-of-the-art processors are still no match for the human mind. The average brain has a storage capacity of about 100 terabytes, while the typical PC offers only a fraction of that, about 100 gigabytes.
The human body has roughly 60,000 miles of blood vessels.The body’s blood vessels, which include the arteries, veins, and capillaries, would be 60,000 miles long if they were laid out end to end. That’s approximately the distance you’d need to travel if you wanted to circle the globe two and a half times.
The human nose can remember 50,000 different scents. Although you’d probably never want to recall that many aromas, it’s nice to know that your nose is doing its job. That said, you shouldn’t be too impressed—humans have about 5 million odor receptors, while dogs, depending on the breed, may have more than 220 million
