Every year, millions of hours and billions of dollars are poured into medical innovation, with new methods of improving, sustaining, and extending human life discovered on a near daily basis - yet without some significant accidental medical discoveries thrown into the mix, many of us would not be here today. Unintended scientific discoveries often prove more fascinating than those made on purpose. Perhaps it’s the lure of serendipity, or the enticing possibility of changing the world for the better through nothing more than sheer happenstance. Either way, people everywhere are grateful that some enterprising individuals were fortunate enough to stumble into important medical breakthroughs - and had awareness enough to understand the implications of their discoveries.
