For 20 Days, This App Connects Two Strangers Who Will Never Meet

20 Day Stranger allows them to track each other's lives...but in an intentionally vague and anonymous way. Its developers say the goal is to increase empathy and understanding.

What's the Latest Development?


Developers at MIT Media Lab's Playful Systems group are working on an iPhone app that they say will use common mobile features to foster compassion and understanding between people. As its title implies, 20 Day Stranger will match two complete strangers and allow them to see descriptions of each other's activities that are intentionally vague (such as "at a cafe" or "near an airport") for just under three weeks. The app uses the phone's sensors as well as general data from services like Instagram and Google Maps to give just enough information without revealing private details such as names or specific addresses.

What's the Big Idea?

The app is the brainchild of Tinsley Galyean, who co-directs MIT's Dalai Lama Center for Ethics and Transformative Values and broached the idea to the development group. "[It] isn’t to make your life transparent," says Playful Systems director Kevin Slavin, "it’s to give just enough to wonder and imagine and ultimately, to care. It is explicitly about producing imagination and conjecture, not transmitting information." Indeed, the app only serves to link two anonymous people who, at the end, will ideally gain some insights into everyday living.

'Upstreamism': Your zip code affects your health as much as genetics

Meet the Bajau sea nomads, who can hold their breath for 13 minutes

The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.

  • The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
  • Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
  • Unfortunately, many disparate factors are erasing the traditional Bajau way of life.

Surprising Science

Time of death is considered when a person has gone into cardiac arrest. This is the cessation of the electrical impulse that drive the heartbeat. As a result, the heart locks up. The moment the heart stops is considered time of death. But does death overtake our mind immediately afterward or does it slowly creep in?
