The study is the brainchild of University of California–San Francisco epidemiologist Mark Pletcher and University of California–San Diego behavioral geneticist James Fowler. They wanted to find a low-cost way to see if time spent ‘liking’ and ‘poking’ on Facebook has either favorable or adverse effects on people’s hearts. So they decided to go straight to the source. They created a Facebook app and started asking people to share their health data and online activity patterns.
