What’s the point of spending time doing nice things for others? Is it purely a feel-good experience for the nice person, or is there a greater impact on others, and on the world in general? In fact, it is official – researchers have shown that generosity is contagious. And not only is it contagious, but one act of kindness is actually shown to breed another act of kindness, and so on. Kindness can multiply and move on from person to person.
