In a retirement home in Florida Pokemon Go is used to keep the senior citizens active and their minds fresh. The app is well known for its bad and good influences since the release a month ago. But in this case it is used for a good cause. The citizens are being challenged to walk more often. This way they find more Pokemon and they are working on hatching their eggs.
I find this a perfect and fun modern way to keep the citizen moving. They have a reason to get up and it is also a really social app. In the video you can see citizens talking about their Pokemon.
All there is left to say is, you go Florida.
