The human body is a remarkable machine that is capable of incredible feats. The heart beats around 100,000 times per day, pumping blood through over 60,000 miles of blood vessels. The brain processes an astonishing amount of information every second, with some estimates suggesting it can handle up to 4,000 thoughts per hour. Meanwhile, the lungs breathe in and out, exchanging oxygen and carbon dioxide through a process that is so efficient that we don't even notice it's happening. It's truly amazing when you think about it!
