Revealed: Why Rudolph's nose is red
Most people know Rudolph the Red-Nosed Reindeer had a very shiny nose — but why? Medical researchers say they've now found the answer. The secret to Rudolph's rosy schnozzle is the dense network of blood vessels in his nose. Reindeer, it seems, have 25 percent more capillaries carrying red, oxygen-rich blood in their nasal architecture than humans, say the scientists from the Erasmus Medical Center in Rotterdam, the Netherlands, and the University of Rochester in New York. "In colder climates and also when they are higher up in the atmosphere pulling Santa's sleigh, the increase in blood flow in the nose will help keep the [nose's] surface warm," Dr. John Cullen of the University of Rochester told MedPage Today. The dense network of blood vessels in reindeer noses is also essential for regulating the animal's internal body temperature — like many mammals, reindeer don't sweat.

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
