I enjoyed skimming through the book "The ESL Miscellany". Stuff like "List 8: Human Relationships": Nouns (admiration, affection, antagonism...), Verbs (admire, befriend, cooperate...) People (acquaintance, antagonist, associate...), Human Qualities and Stages (aloof, artistic, attractive...), Stages (adolescent, age, aged...), Idioms and Expressions (have an affair, blind date, breaking up...)
To give you a sense of size, think of one of your own trillions of human cells, or a solitary amoeba or single-celled alga, as the size of a small city. Then a typical bacterium or archaean would be the size of a football field and a virus the size of a football.
Parasites, in a phrase, are predators that eat prey in units of less than one.
