Height

You are shortest in the morning, and tallest at night.
Another amazing fact that you may not know is that when you get up in the morning, you are actually taller than you normally are! This incredible occurrence is because during the course of a day, the gravitational pull pushes on your spine, along with other parts of your body. As you go lay down, your body then is no longer being ‘dragged down’ by gravitational pull, making your body go back to it’s normal size laying down!
