You don't get flu, if you get wet and cold after rain. Especially if you are normal, healthy person who doesn't have any terminal disease. Viruses cause diseases. I thought that was basic knowelege. I tried to be funny saying pollution makes it happen but my english is not so good, so maybe my joke is not understanted.

I know "getting sick when walkin in rain" is popular trope, but its just lazy writing. Is pollution so bad that perfectly healthy person gets so much viruses from it that they get sick right away. I get why it is used, but it's as cringe as getting nosebleed after seeing some sexy person.
