Fun Facts about Parasitic Worms

Did you know that there are parasitic worms that get into your blood or lymph vessels and stay there? Imagine looking down at the veins in your hand and noticing that one of them is moving. It's shifting and squirming. Oh god, there's something inside there. Get it out, get it out! But you can't. There's no way to do it without cutting open your vessels, and you really don't want to do that. So you need to wait. Wait until the antiparasitic works, and pray that it does.

There are also worms that pierce through your skin and make their way to your lungs and when you cough them up, see the writing mass of worms crawling all over your hands, they use it as a way to go back down the other way & get into your digestive system to breed. You may very well have had these worms at some point too, they're apparently pretty common.
