Sometimes our lives get so busy that we forget to appreciate the wonders of the body and everything it allows us to do. But the truth is that you are alive because of brilliant biochemistry, and as you go about living your life, 60,000 miles of blood vessels run through you, and your body is producing 25 million new cells each second.
What's even more amazing is that the trillions of diverse cells in your body were formed from the same carbon, nitrogen, and oxygen in stars that shined brightly billions of years ago. In other words: You are literally made of stardust. And while these trillions of cells all have their own unique purpose, they also have one thing in common: They need vitamin D to thrive.
