Malaria has killed over 100 Million people since the late 1970′s.

Capgras Syndrome is a psychological condition in which the affected person believes that a loved one has been replaced by an impostor.

They sincerely believe that the impostor has replaced someone close to them, and are often combative toward that person.

In one instance, an affected man decapitated his father to prove that he was really a robot. (He wasn’t.)

The woman I saw on TV last night was adamant that her husband of 31 years was replaced in some type of conspiracy. They still lived together, but he was forced to remain in a few rooms on “his half” of the house. She was openly hostile toward him, and refused to believe he was really her husband.

The disorder is named for the French doctor who first confirmed it was a real condition.

Put this on the list of stubborn diseases that just won’t go away. In 2007 there were over 250,000 cases of leprosy diagnosed in the world.

But the good news is that it seems to be on the way out the door, because there were over 750,000 cases in 2001. The number of new cases has been steadily decreasing since then.

Leprosy, which is featured prominently in the Bible and has been plaguing mankind since 600 BC, is caused by a bacterial infection.

Fortunately, 95% of the population is naturally immune, and today the disease can be cured in most individuals with a simple cocktail of drugs.

But, if you are paranoid about these types of things, you may want to avoid Brazil, India, Nepal, Tanzania, Madagascar, and Mozambique. Oh, and even though we still technically don’t know how the disease is spread, you may want to avoid contact with Armadillos.
