You can always spin the story of working full on science at CERN is in fact, also helping people. Though the help is for the future. But still, helping (assuming what comes out from the fundamental research at CERN will be turned into something good and therefore helpfull to people) 🙂

Of course I did it. But below 10, kids have a different perception of life. Physics help to shape problem solvers, and those are very deeply needed in our societies...
