Disease

Whether its curing existing diseases or encountering new ones, a bit or a lot of pathology doesn’t hurt a story or make for a bad plot device. Injecting fear and dread into any scenario can be as easy as prescribing an epidemiologist or two.

The scope in speculating future disease can again be endless, e.g microbial, fungal, genetic, psychiatric, crystalline extraterrestrial agents, or cyber infections
