The Paleolithic Era (or Old Stone Age) is a period of prehistory from about 2.6 million years ago to around 10000 years ago. The Neolithic Era (or New Stone Age) began around 10,000 BC and ended between 4500 and 2000 BC in various parts of the world.

MLK was an American Baptist leader and also an activist. If I had to choose one thing that interests me most, is how he captured attention of the nation. How he could stand up, yet still survive as long as he did, doing the dangerous work he did. One time, a young(german) Nazi came onto his stage and started beating MLK. Yet, in less then 20 seconds MLK was hugging the Nazi, and he didn't even get a penalty.
