On the day the United Nations has designated International Day of Happiness, we asked our viewers to send in photographs of what makes them happy.
If these are anything to go by, children, animals and sunny weather are the most common causes of happiness.
(But for some people, it's black pudding - and porridge.)
These people in Jesmond, Newcastle, told our reporter what makes them happy.
