All good points, parasites are generally to be avoided and do have consequences. As for tapeworms, it really depends on the type. Some as you say just eat your lunch, but pork tapeworms are dangerous. They carry a risk of having their eggs wend their way into tissues such as muscles, and most dangerously the brain, with predictably disastrous consequences. Neurocysticercosis is no joke, and if you’d like to never sleep again try a google image search for it. The only two (controversial) benefits of human parasites I know of are non-pork tapeworms used for dieting, and... something very interesting indeed. I give you... Helminthic Therapy. Some clever folks noticed that certain parasitic worms (helminths) are very good at modulating the immune system of their host, presumably to protect themselves and their offspring. They reasoned that a controlled infection could help with some autoimmune diseases, and it’s a subject of research. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5401880/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5401880/ Even more interesting though is the hypothesis that widespread helminth infection is a contributing factor to lower rates of allergies and autoimmune disease in developing nations. https://en.m.wikipedia.org/wiki/Helminthic_therapy https://en.m.wikipedia.org/wiki/Helminthic_therapy
