A Belgian girl returns to the vaccination center where she received her first dose of vaccine the day before, after realizing that her smartphone, which has a metal shell, was magnetizing at the injection site of the vaccine. It also works with other phones. In addition, data from her phone book disappears for about 10 minutes, every time she brings her smartphone close to the arm that received the injection (she still has the names, but all the phone numbers disappear). The doctor is unable to give her an explanation, the only (stupid) thing he is able to tell her is "you may be more sensitive than others to magnetism". The workers of the Center all come to see the curiosity and laugh about it...
