Our current level of knowledge says that Chaos is too unpredictable to support life. Given this, Chaotic memes are not alive, but I'm not sure I'd call them viruses.

Fitness is based on how long an individual can walk without bumping into a wall.
Individuals know how to go forward, backward, left and right. The also know how to detect a wall. Spinners simply spin in circles. No matter what maze they're put in, they always walk and never hit a wall. Therefore they always receive the highest level of fitness.
