Human beings have about 25,000 genes which make up the cells in our DNA. Often times through genetic mutations, our DNA is defected causing different things to happen in the human body. No, I am not talking about mutants like the X-Men, but real disorders like Cystic Fibrosis or Down Syndrome. Genetic mutations can also cause addictions, for example to alcohol or nicotine. A new study though shows that the addiction to the Internet works in a similar way, through a genetic mutation.
