Eating lunch at your desk can be a real downer, report scientists from the University of Sussex who measured the happiness of employees after they ate lunch in different locations. 

The results showed that workers were happiest about their work when they ate lunch on the beach and least happy about work when they ate at their desk.

Getting outside in the sun was key to staving off misery — people who ate in parks had a more positive attitude about their jobs than those who chowed down at a restaurant or at home.
