They say the nose knows, turns out, it knows a lot more than we think.

Now new research from Rockefeller University finds the human nose can detect at least one trillion odors!

Most experts previously thought our noses could pick out about 10,000 smells.

For sensory comparison, the average eye can see a few million colors and ears can detect about 340,000 tones.
