let me guess, you got this from playing Plague Inc. (https://play.google.com/store/apps/details?id=com.miniclip.p...) on your phone, right? ...the game is so unrealistic that it almost annoyed me to the point of motivating me to write a competing more realistic game ...but then I realized that "more realistic" would be too detrimental to the gameplay for it to be enjoyable :)
