"Spending as little as $5 a day on someone else can make you happier," the researchers from a team at the University（大学）of British Columbia and Harvard Business School reported.

    Their experiments on 600 volunteers in the US showed people were feeling happier when they spent money on others.

    The team asked their 600 volunteers about their income（收入），their daily costs, gifts for others and donations to charity. "No matter how much money each person made, those who spent money on others could get greater happiness than those who spent money only on themselves," Dunn said.

     Dunn's team also surveyed 16 workers at a company in Boston after they received an award of between $3,000 and $8,000. "Of course they felt happy after receiving the awards," they wrote in their report. "But when they gave the people in need $5, they were happier."

     "The findings showed that as little as $5 could be enough to produce happiness on a whole day," Dunn said.
