Jim Fixx's Shorts

Origin
Jim Fixx was an American who authored the 1977 best-selling book The Complete Book of Running. He is credited with helping start America's fitness revolution, popularizing the sport of running and demonstrating the alleged health benefits of regular jogging. He died of a heart attack while jogging at 52 years of age. His genetic predisposition for heart problems and other previous lifestyle factors may have caused his heart attack.

Effects
The shorts release a variety of stimulating endorphins that positively affect attention, mood and happiness, causing euphoria. However, it worsens pre-existing heart defects and should not be used by anyone with cardiac issues.
