A recent report from a games industry analyst suggests that among a number of factors leading to the purchase of a video game — such as price, graphics and word of mouth — the game's aggregated review score is the least important measure. Analyst Doug Creutz said, "We believe that while Metacritic scores may be correlated to game quality and word of mouth, and thus somewhat predictive of title performance, they are unlikely in and of themselves to drive or undermine the success of a game. We note this, in part, because of persistent rumors that some game developers have been jawboning game reviewers into giving their games higher critical review scores. We believe the publishers are better served by spending their time on the development process than by 'grade-grubbing' after the fact."

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."
