Neurologists believe that our brains are set out to bring pleasure. Studies have also found objective proof that when we spend money on others, we experience a greater sense of satisfaction than when we spend the money on ourselves. The smile on the recipient's face when opening their gift provides another person with a psychological boost and stimulates the release endorphins into their brain, creating the same euphoric feelings of satisfaction and happiness that we can encounter after a good workout or when we fall in love.
