The state of the economy may be out of people’s hands, but their happiness isn’t, according to a group of researchers meeting at an international conference on happiness Thursday. Experts from fields ranging from neuroscience and philosophy to psychology and theology will gather to discuss the latest insights on living happier lives at the meeting in Sydney, Australia. Drawn to workshops with titles like The Architecture of Sustainable Happiness and Practical Tools for Positive Relationships, more than 2,000 participants are expected to attend the conference.
