Here’s an interesting story of the guy who creates bullet-proof vests. What’s interesting is his story as a pizza delivery boy.
Richard Davis, former U.S. Marine and onetime pizza delivery guy in Detroit, survived a gun shootout (he killed three armed robbers when they attacked him during a delivery). He went on to develop new forms of concealable body armor using kevlar. Those products are now widely used by military and law enforcement personnel, and private sector folks who have reason to believe they will be shot. This video tells a bit of his life story.
