Ok, moving to Switzerland might not make you happy, but people who live there are some of the happiest in the world, according to the 2015 World Happiness Report, a ranking compiled by an international team of economists, neuroscientists, and statisticians to measure global well-being.

One of the report's key findings, based on decades of neuroscientific and psychological research, suggests that keeping the brain happy relies on 4 main factors, which include staying positive, recovering from negative feelings, spending time with loved ones, and being mindful.

"These findings highlight the view that happiness and well-being are best regarded as skills that can be enhanced through training," the researchers write in their report.
