One of the biggest challenges human beings face in this life is being able to breathe effectively and efficiently. Breathing is one of the first things we do at birth and is usually the last thing we will do before death. If we are unable to breathe correctly and efficiently we begin to succumb to the force applied on a non living mass and, eventually, we are unable to continue without support. Astronauts face similar struggles as their bodies are subjected to improper forces and a lack of movement, both of themselves and the air around them, within their confined areas.
