I don't care what anyone says, I am not eating BUGS. No bugs. No worms. No... scorpions. And definitely no parasites that feed on the blood of other people. In my culture, bugs are generally not considered a snack, just like monkeys, horses, dogs, cats, rats, mice, and even guinea pigs are not seen as food animals.
I don't even like eating crabs or lobsters, which are like really big bugs. Although sometimes I'll eat a shrimp or two.
And I've heard about how the near future we'll have to eat bugs there won't be anything else to survive on. All the reason I shouldn't eat them NOW. 
I did just read, however, that head lice are actually harmless and carry diseases, and that they may even help people become more resistant to more dangerous types of body lice. But like that's going to make me want to get head lice. Sometimes I'm even nervous to try on hats when I'm out shopping.
