I don't like it when companies collect data on me just so they can sell more things. But what if data collected on us is used to help people?
GPs will soon gather heaps of patients' medical records from all over the country. But don't worry, this won't contain names or addresses.
The NHS will trawl through this huge amount of data and build a big picture of health services in the UK. I like that my data will be used to improve people's health.
