Something to fill the time: #Infographic: Olympic Players Disqualified For Drug Use

There are some relations between the use of drugs by sports players with drug use by warriors and soldiers. Both go back through history, and perhaps prehistory. It appears that using substances, both natural and synthetic, in order to improve the senses and energy levels has been a consistent drive in humans. The desirability of performing better in a variety of situations - even the instinct to kill and survive combat - is a part of humanity as well.
