[Leica] IMG: Why I Keep on Ticking

[Jim Nichols]

While searching for something today, I came across a sample of the 
mechanical heart valves that I had implanted in 1993.  Young nurses with 
sharp ears could hear them ticking from across the room.  When I had a 
stress test earlier this year, one of the nurses finally asked, "What am 
I hearing?"  This is 1990s technology, but, in the spirit of Halloween, 
I thought someone might be interested.
