Let's be honest. People love killing time with mobile games. And what is the best time-killer? It's cholesterol. It builds up in arteries when a person consumes junk food, alcohol, or cigarettes. Eventually, cholesterol may cause a stroke, which will literally kill your time. As a way to pique interest in the cholesterol problem, Orbi Stroke Foundation crafted a game that's as ironic as it is entertaining - Colesterunner. In this game, the character embarks on a journey through arteries, collecting items that humorously represent an unhealthy lifestyle, such as junk food, alcohol, and a couch potato lifestyle. The goal of the game is to kill the organism by blocking arteries. While playing, users learned how cholesterol works and how to dodge its harmful effects in real life. Thanks to the irony, the game immediately went viral, helping people learn more about boring but serious problems in a fun way.
