Are you in process of building your own house? - How can you keep luck on your side and bad spirits away. Here is the true bolivian solution:
Visit the witch market in La Paz, you'll find it along and around Calle Santa Cruz in the center of the city. Look out for a nice size Llama fetus. - Yes, no kidding. - Negotiate the price with the witch - eh, sorry - the sales person...
Take the dried creature home with you. Make sure it sits as much in the center as possible of the concrete foundation of your future home. Once as solidly covered in cement as the feet of disobedient Mafiosi in Siciliy before exploring the Mediterranean, it will protect you and your family and any one in your house from bad sprit and guarantee you luck as long as you live in that house.
What are you waiting for?
