Wait a minute. Wait. A. Minute. (Fellow Whovains will get this.)
So, since I have a different body than I did 7 years ago, doesn't that mean that humans technically regenerate every 7 years?!
Different body? How do you explain these scars? And 1000 Terabytes is a Petabyte. Oh how I wish America would bite the bullet and adopt the metrics system. In third grade I had a dream about a fucking Vampire. I guess I just forgot about that casual run in. If your brain is able to create places that don't really exist why not people? The eyes are the strongest muscles in your body. Where is all my arm hair going?
