From what I can tell, Bolivians as a whole tend to be a fairly paranoid bunch.
Rachel and I happened upon this topic before she left and we compiled a fairly long list of weird superstitions and instructions that we had heard since our arrival.
Here is the gist:
1. Don´t sleep with the fan pointing towards you. It sucks the air out of the room. Point it at the wall instead.
2. If you´re going to sleep with the fan on you must also cover with a light blanket. Otherwise you´ll get sick.
3. When riding in a bus always have the window open for fresh air. Otherwise you´ll get sick.
4. You must always have shoes on while walking on tile floor because the `cold´will enter through your feet and reach your head and make you sick.
5. When you buy a car you must cover it with ribbons and bring it to the priest to be blessed. If you don´t own a car, but would like to, bring a miniature car to the priest and have it blessed.
6. If you have a fever you must cover yourself with blankets no matter how hot you are.
7. If you have a fever, drink mate de coca (coca leaf tea)
8. If you have altitude sickness drink mate de coca.
9. If you have a stomach ache drink mate de coca.
10. If you have a headache drink mate de coca.
11. Interestingly enough, if you have a virus you should drink raw egg and freshly squeezed lemon juice every morning at 4:00.
After rereading the list, I realize that I have followed all but numbers 1, 5, & 11 fairly regularly since I arrived. Maybe they aren´t so ridiculous after all.
