Haha, if you think we are dirty now... just go back in time 40 years, or 60, or a thousand. People are dirty. E.Coli has existed forever, yet here we sit, the largest population ever. The point of this global study was to sell soap and convince people that showering one time a day isn't enough. Or maybe to fear monger. Either way, I would be interested to see if the party who payed for this is happy with the results. Or you know, if they know their money went to a study that was pointless.
