Order IMMUNE here: https://kgs.link/ImmuneBook – It’s available in English and German and at online retailers it should be available in pretty much all countries too. Sources & further reading: https://sites.google.com/view/sources-immune2/ You are not a person, you are a planet, made of roughly 40 trillion cells. There is so much of you, that if your cells were human-sized, you would be as big as 20 Mount Everests. For your creepy-crawly inhabitants, this makes your body an ecosystem, rich in resources and warmth and space. A perfect place to move into and have a family. While some of these guests are welcome, most are not. Your immune system is the guardian of this planet, the force tasked with protecting yourself against the constant danger of invasion.
