It very similar to all of us, except it stays together and works as a team. We, on the other hand, fight amongst ourselves waging war against other communities. Imagine, if we had the power to act as they do. We would all stick together, expand, fight our enemies, and simply survive. Those little cancer cells, might know something, we don't. It's called, self preservation.
