Evidence that Some Scienctists are Right

So I've long heard that people shrink a little bit during the day (for more info on that phenomenon, click here), but I never really put much thought into it until recently. Why, you say? Well, in the morning when I get into my car I find that I have to move my rear-view mirror up a little bit. At night after work, it's just the opposite, I have to move it down. Either I'm slumping a lot due to the stress of the day or my vertebrae really are compressing due to the constant force of gravity throughout the day! Nerdalicious!
