Tibetian Lung Cancer

A disease that is easy to recover from, but tends to have lasting side effects. Some of the negative effects of TLC can include a painfully large inflation of the ego (which can be cured by large doses of humility). Also, TLC tends to cause allergies to losing. (which can result in anaphylaxis)
