Happiness is literally contagious! That's according to a new Harvard/UC San Diego study!
You may think your own experiences form all of your happiness, but this new research claims if your friends or even your friends' friends are happy, it rubs off on you too!
When researchers observed over 50,000 social and family relationships and analyzed the spread of happiness throughout the group, they found the effect filtered out up to three degrees, meaning the benefit reached their friends' friends' friends.
They found it lasted for up to one year, and was stronger the closer the two people lived to each other.
