5 Second Rule!

 What most people don't realize is that the "5-Second Rule" actually comes from the medical community.  Surgeons, in fact.  As they get farther into a surgical procedure, doctors will typically find their gloved hands covered with some amount of blood, and hanging on to a surgical instrument often proves difficult, particularly as you switch from one tool to the next.  The transfer can get messy.  

Dropping a scalpel, for example, is a fairly regular occurrence and upon hitting the floor, doctors will often shout "5-second rule!" and bend down and pick it up.  With slippery hands, these fallen instruments can sometimes be hard to pick up off the floor within the established 5-second "latency period."  The ability to internally recognize a 5-second interval is one of a doctor's most under-appreciated skills.  This inner sense of timing is part of why so many doctors are also excellent musicians.

So the next time you accidentally drop your delicious treat on the floor and eat it within 5 seconds, remember its medical roots!  Well done!
