On the health front, that's really very interesting.
When you go to the hospital, there is a file about you on site. That file is shared, or it is not. If you change physicians during your life, it unfortunately happens that files are not transmitted in their entirety, or that the information they contain is not sufficient.
Digital health data should be compiled in a file that would follow us all our lives. It would be more practical and safer for people. What do you think?
