Our Future Health
Our Future Health is a health research project in the United Kingdom run by  iPLATO.  It uses the the NHS App.  It aims to recruit 10% of the people, about 5 million, to be a fair sample, with people from  all sorts of  socioeconomic and ethnic groups.  The project is to last 10 or 20 years.  People who volunteer must visit a clinic where they are given tests. They give blood samples, and their weight, blood pressure and cholesterol are measured, and their DNA is analysed.
