Mission unstoppable

Today it was a quick episode of mission unstoppable. I learned about animal bones, the brain, a prank to pull on your friends and how, and how an ancient civilization made better replacement bones than we do now. Animal bones, I learned how to distinguish how a animal died. You can tell by the markings on the bone, if it was a strait line or a shattered part, it was most likely a hunter with a bow. But if it was a little indent it was a animal. Secondly i learned about how the brain reacts to pain. What happens is the nervous system tells the brain what to do and how to act. I also learned if you were to pick a number between 1-10 then multiple it by 9, then ad the two numbers you get 9. Lastly i leaned how people used to put broken shards of seeshell in their mouth to replace teeth.
