Leider nein . Ich schlafe jede Nacht mit Trnen in den Augen ein , weil ich kein Student mehr bin . <| sep |> I would definitely stay away from protein powder then . That stuff will make you look like a bodybuilder after a few weeks ! Focus on the eliptical <| sep |> I think it ' s reasonable to assume that someone you meet for sex isn ' t actively trying to infect you . <| sep |> There are definitely many things that have similar effects there are many types of plagues , curses , etc . but they are mostly created by intelligent creatures and based on magic . Many animals and plants have poisons that cause death or illness . But viruses ? They don ' t really seem to be a thing . If they worked how they do IRL , when the orcs invaded Azeroth most of them and many creatures they came in contact with would suffer , because they weren ' t used to local viruses and they brought from Dreanor ones the local environment wasn ' t used to . So I personally guess viruses don ' t exist there . Cancer is something different , though . It ' s basically cells not working properly and multiplying far more than they should . Well , we know that most of the types of power in the Warcraft universe can cause physical and mental changes , mutations . We also have many types of corruption Old God corruption , fel corruption , etc . With so many ways for mutations to occur and some of them being so unpredictable and negative for the being Old Gods ' influence again it seems likely that something like cancer would appear there . It ' s possible that it just isn ' t widely acknowledged as a big problem because of how strong the mutations are most creatures affected by them are very aggressive , which leads to them being quickly killed . We keep killing such mutated creatures , without fully testing how the corruption works . Well , but if it comes from those kinds of power or corruption , it should appear in creatures that use those things a lot , Mages , Warlocks , etc . Well , their profession is based on controlling this power . IRL cancer is caused by radiation , which we can cause but can ' t reliably control . In other words many creatures aren ' t ever under the influence of cancercausing effects , some others can control them and as such stop their influence on themselves and the rest gets mutated so far that it just gets killed because it ' s considered a threat .
