Conspiracy

It is a massive conspiracy

I'm sure there has been independent research into developing new parasite drugs, but most funding has no doubt been suppressed. They don't want us better at all for many reasons.

I have a friend in the field whom I asked this question to. He said it sounded like a good idea but admitted that the medical field itself often makes it sound easier to rid oneself of parasites than it actually is. Especially in the US. It is a lot of guess work.
