Above is a link to this article on online networking and health issues.

"Dr Aric Sigman says websites such as Facebook set out to enrich social lives, but end up keeping people apart".
"He also says that evidence suggests that a lack of face-to-face networking could alter the way genes work, upset immune responses, hormone levels, the function of arteries, and influence mental performance". The implications of these alterations can have a serious impact on your health. Dr. Aric goes on to say that it displaces people and isolates them physically meaning people will lack skills to read body language impeading our social skills.
My question to you all is... Do you find this imformation factual?? It was a peer reviewed and published journal by the institute of biology.
