Feel-good, do-good phenomenon

the feel-good, do-good phenomenon is interesting to me because i wouldn't have guessed that someone's emotional state can have such an effect on their actions. this is a picture of a woman being helped out of a boat and you can probably safely assume that the man helping her out is in at least a decently good mood.

Feel-good, do-good phenemenon: people's tendency to be helpful when already in a good mood.
