While there has been some debate over the use of the Rumor Mediocris' parietal lobe to conduct information from one test subject to another. I can insure you all that through my research and endless experimenting, there is only a very slim to almost minuet chance of the users temporal lobe being effected. And an even smaller chance of the brain steam bleeding for extended periods of time.
Of course, with any new device we avid members of the scientific community create there will always be those who fear progress or will make claims that such advancements will damage the user or the environment. However, such radical and unproven claims will continue to fall upon the deaf ears of the educated and brilliant minds of our modern era.
