The nose is an amazing piece of the human body. Every flower or food gives off odor molecules that your nose picks up and your brain translates. Approximately how many smells can your brain recognize?
Answer 1,000,000,000,000
The nose has the ability to differentiate between about a trillion different smells due to different combinations of odorants. Unfortunately, though, scientists aren't sure that it matters all that much because there might not be a trillion smells in existence!
