Mutations?

I didn’t always look this way. Actually I used to be described as attractive. Today I’d give anything to just look, well… normal. How did I come to be this way? Well that’s one long and complicated story.
In 2012 I was part of a team of 7 astronauts sent on a unprecedented privately-funded mission, by multibillionaire Kenneth Brussels, to search previously unexplored areas of the moon for alien life forms.
To Mr. Brussels it was merely an investment. If we were to find an extraterrestrial being he planned on creating some kind of zoo where he would charge people to observe. To the seven of us it was an opportunity to find the very reason we pursued our career as astronauts, our childhood dream of someday discovering a different life form.
We came back that same year after months of searching and believed the whole enterprise was a failure. Until a few weeks after our return, something happen. One by one all seven of us began experiencing bizarre symptoms, such as foreign growths and mutations all over our bodies. We must have found an alien after all, or maybe it found us. It seemed to be some type of pathogenic bacteria that was continually altering our bodies. It could not a communicable disease because we had already spent at least 2 month on earth... (hmmm... i dont know where this is going)
