Hairstyles: As Explained by SCIENCE

Mohawk: Energy and mass are formed at the center of the system in a gaussian distribution. Certain compounds are required to maintain this state. H2O works for a few seconds, more powerful adhesives are required for extended periods of time.

Combover: Some energy and a lot of mass is moving from areas of high to low concentration.

Afro: A chaotic system. The laws of thermodynamics break down at this energy level.

Dreadlocks: When an afro "cools down" after a long period in a chaotic state, it eventually forms an incredibly static system. The only way to alter the state of a "dreadlocked" system is to destroy it completely. Whoever figures out why will get a free trip to Sweden.

Bedhead: This is a strange system, although it appears dynamic, occasionally static pockets emerge. H2O can return this system to a more stable state.

Parenting

I'm starting to think that giving birth to a child (or fathering one) results in either a breakdown or complete brain takeover of the limbic system.
