Never face a cold stethoscope again...

In the department of interesting things you come across, I was surprised at the many different types of stethoscopes that existed for sale, littman stethoscope as one example. I also discovered that there are even ones that are designed to not be cold which for me is one of the experiences I hate when I go to my family doctor. It seems to me at times he purposely keeps the thing in a freezer in between patients so that I'll have to gasp when he listens to my heart. Adds a twist to the whole "take a deep breath" scenario....
