Finally, kindness makes you a happier person. A study done by the University of Pennsylvania showed that when one person shows kindness to another and is able to see the happiness on their face, the happiness you yourself experience can last for up to a month after! Another study conducted by a Japanese university showed that kindness is directly correlated to happiness in the sense that kindness is a direct contributor to happiness.
The research speaks for itself, practicing kindness makes you happier. If not for anyone else, be kind for yourself and your own well-being, it is certain that you will not regret it!
