PHILADELPHIA (CBS) – Sorry, Rudolph, but your famous nose is not very unique.
Reindeer actually have very red noses, according to a report in the British Medical Journal.
They used a hand held video microscope and they studied five healthy human noses and compared the blood vessels density to that of two normal reindeer noses. It turns out reindeer have 25-percent more nasal blood vessels than humans.
So Santa knew what he was doing when he picked the reindeer with the reddest nose of all. Reindeer also have more mucus glands and it helps maintain a moist nasal climate.
