The human body is a marvel in organic possibilities. The evolutionary process has put us at the top of the food chain for a reason. Yet as good as this bio-system is, it is not without its difficulties. A soft shell of flesh and bone with a strong defense mechanism to keep out harmful bacteria, pathogens and diseases serves us well, but it may not be well suited from other planets or environments.

A powerful immune system has worked well on Earth and adapted along the way to defend against most local planet threats, however what about another planet with a different set of threats? What about a clean environment such as a space capsule one, which starts out perfectly clean but the absence of gravity allows some bacteria to grow faster than other normal immune system bacteria in our bio systems?

Indeed the human body appears on the surface to be a very efficient design taking millions of years of evolution to create, yet in terms of different environments it is not the best possible model.

Therefore we will need to make a little human modification to reduce food intake and consumption and limit human waste, as whatever is not used by the body will be discharged, but there will be little space to hold it and we will need to make it into something else we can use during the space flight to a far away world. Think on this in 2006.
