You Are Immune to Every Illness

You are a planet made up of about 40 trillion cells, not a person. You are so large that even if all of your cells were human size, you would still be larger than 20 Mount Everests. This transforms your body into an environment for your creepy-crawly occupants, one that is full of supplies, warm, and space. a wonderful spot to settle down and start a family. Some of these visitors are permitted, but the majority are not. Your immune system is responsible for defending you from the ongoing threat of invasion, acting as the planet's defender.
