Springing clocks forward by an hour this Sunday, traveling across time zones, staring at a computer screen late at night or working the third shift are just a few examples of activities that can disrupt our daily, or circadian, rhythms. These roughly 24-hour cycles influence our physiology and behavior, and they're driven by our body's network of tiny timekeepers. If our daily routines fall out of sync with our body clocks, sleep, metabolic and other disorders can result.

Do violent video games such as ‘Mortal Kombat,’ ‘Halo’ and ‘Grand Theft Auto’ trigger teenagers with symptoms of depression or attention deficit disorder to become aggressive bullies or delinquents? No, according to Christopher Ferguson of Stetson University and independent researcher Cheryl Olson from the US in a study published in Springer’s Journal of Youth and Adolescence. On the contrary, the researchers found that the playing of such games actually had a very slight calming effect on youths with attention deficit symptoms and helped to reduce their aggressive and bullying behavior.
