I just ran across these facts:
Bananas possess just one chemical, which when you smell it you say, "That's a banana." Tomatoes, on the other hand, produce more than 400 chemicals, and by some very complex means our Lord Jesus creates the smell we call "tomatoes." Finally, the aroma of coffee has something in the order of 800 different compounds
that create its unique odor. And the number of new chemicals that scientists are discovering in coffee each year continues to grow!
