The spine is an amazing part of your body. It’s extremely important to your everyday life because you can’t live without a spine. Here are some pretty interesting facts about your spine:

• Cartilage in your spine can expand and contract: Gravity causes your spine to expand and contract. That’s why when people go to space they can sometimes come back taller.
• Baby’s spines begin developing 2 months after conception: The spine is actually the first bone in a body to grow when a baby is in the womb. 
• The spine is super flexible: Your spine can bend back far enough to make ⅔ of a circle.
