Researchers from a University in Europe have discovered that your friends from age 10 – 18 are the ones to blame (or praise!) for your behaviour today.

Before age 10, it’s mostly your family that influences who you are and the decisions you make.

Friends made in intermediate and high school years sway your inclination towards making riskier decisions like partying, breaking the law, smoking, and other ‘adult’ things – as well as impacting your beliefs and morals.

The more popular friends tend to be more influential, but there are a range of factors that dictate how much ‘power’ one friend has over their buddies.

Unfortunately, but not surprisingly, researchers found that bad influences are more powerful in changing behaviour than positive examples are.

But what if the behaviour that we have now is not from our friends but that of our cousins cause they are our first best friends?
