The Metro disease
I am sick of being sick! There are two major factors as to why faux-Parisians like myself frequently get ill:
1. Lack of Vitamin D since weeks go by without sun. Stock up on vitamin D supplements.
2. Public transportation. Think about it; Paris is the no. 1 destination in the world. There are many, many people from all over who visit and bring germs and viruses along which faux-Parisians are unimmune.
This could be why there is a pharmacie on every block in Paris!
